Product Description

PCB Antenna, Antenna PCB, Printed Circuit Board Antennas

Antenna is an important component for all kinds of smart devices, and it is necessary for all devices that need to use wireless. Now is the wireless era, network routers are wireless WIFI, computers, mobile phones no longer need to connect to the network wires, as well as Bluetooth headset, Bluetooth mouse, Bluetooth keyboard and so on no longer have wires, the performance of this antenna is crucial.

In general, there are some factors in antenna selection. In addition to performance, the cost should be considered. Therefore, when choosing antenna, comprehensive consideration should be taken.


What is an antenna?


Antenna is a kind of converter, which transforms the guided wave propagating on the transmission line into electromagnetic wave propagating in unbounded media (usually free space), or performs the opposite transformation.

The antenna is a component used in radio equipment to transmit or receive electromagnetic waves.

Radio communication, radio, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems, which use electromagnetic waves to transmit information, rely on antennas to work.

In addition, in the use of electromagnetic waves to transmit energy, Non-signal energy radiation also requires antennas.

Generally, antennas are reversible, that is, the same antenna can be used as both transmitting antenna and receiving antenna.

The same antenna is the same as the basic characteristic parameter of transmitting or receiving. This is the reciprocity theorem of antenna.


What is Radio Wave?


Radio wave is a form of energy transmission. In the process of transmission, electric field and magnetic field are perpendicular to each other in space, and at the same time, they are both perpendicular to the direction of propagation.


Radio Wave Principle



Classification of Antennas


1. The antenna can be divided into transmitting antenna and receiving antenna according to its working nature.

2. It can be divided into communication antenna, broadcast antenna, television antenna, radar antenna and so on.

3. Directional antenna can be divided into omnidirectional antenna and directional antenna.

4. According to the working wavelength, it can be divided into ultra-long wave antenna, long wave antenna, medium wave antenna, short wave antenna, ultra-short wave antenna, microwave antenna and so on.


Microwave antenna


5. According to the structure and working principle, it can be divided into wire antenna and plane antenna. The characteristic parameters of the antenna are pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization and bandwidth.

6. According to the Dimensions, it can be divided into two types: one-dimensional antenna and two-dimensional antenna.

One-dimensional antenna: It consists of many wires, such as straight lines used on mobile phones or smart shapes, like rabbit ears used on TV before cable appeared. Unipolar and bipolar antennas are two basic one-dimensional antennas.

Two-dimensional antenna: Various, there are flakes (a square metal), arrays (a bunch of well-organized two-dimensional patterns), trumpets, dishes.

7. Antennas can be divided into three categories according to the different occasions of use: handheld antenna, vehicle antenna and base station antenna.


Base station antenna


The Difference Between dBd and dBi


The gain of an antenna compared with a symmetrical oscillator is represented by "dBd", and the gain of an antenna compared with an isotropic radiator is represented by "dBi", for example: 3dBd = 5.15dBi


What is PCB Antenna?


PCB antenna refers to the part of PCB used for wireless reception and transmission.

Antennas are critical components for many wireless systems, with printed circuit board (PCB) antennas leading the pack due to their small size and ease of integration with other high-frequency circuits.

In circuit design, the antenna circuit is designed as copper wire on PCB instead of antenna.

PCB antenna is the most low-cost, medium-sized antenna, as long as properly designed can obtain sufficient performance of the antenna.

The performance and consistency of a PCB antenna depends heavily on the quality of its foundation circuit laminate, with size very much a function of the target frequency and wavelength of the antenna.

Antenna is a transducer.

When transmitting, it converts the high frequency current of the transmitter into space electromagnetic wave; when receiving, it converts the electromagnetic wave intercepted from space into high frequency current and sends it to the receiver.

Antenna design is an important part of the design of a low-power, short-range wireless transceiver used in radio frequency identification system.

A good antenna system can make the communication distance reach the best state. There are many kinds of antennas. Different applications require different antennas.

In the low power and short distance RFID system, a reliable and inexpensive antenna system is needed. PCB ring antenna is one of the most commonly used antennas. See the figure specifically:


Fig.1 PCB ANTENNNA

Fig.2 PCB ANTENNA


Fig.3 PCB ANTENNA



PCB antenna is widely used in Bluetooth module, WIFI module, ZIGBEE module and other single band module circuit board.

Advantages: There is almost no cost and no need to debug again after one adjustment.

Disadvantage: Only suitable for single band, such as Bluetooth, Wifi. The performance of PCB antennas in different batches will have some deviation.

At present, the most popular printed circuit board antennas are the loop, patch, inverted-F, and meander line.


Types of Antenna PCB


PCB patch Antenna


Patch Arrays antenna PCB


On the surface, devices with wireless capabilities seem like they would be pretty complicated.

However, you can use some simple solutions to add wireless communications to the next PCB.

If you're looking to add GPS, WiFi, or other communication capabilities to your next electronic device, you might consider adding a patch antenna to your PCB. These inexpensive components are readily available and are easy to incorporate into your PCB. If you're really feeling creative, you can add a microstrip patch antenna to your board, giving you wireless capabilities that are directly integrated on your PCB.

PCB Trace Antennas


Printed circuit board trace antennas are notoriously difficult to design, implement, and tune; particularly in a small and reliable implementation. Similar to a wire antenna, a trace antenna's size will depend on the frequencies of the target bandwidth. For example, at low frequencies, the length of the trace antenna will have to be much longer for the signal integrity to resonate.

High-frequency PCB Antennas


High-frequency PCB antennas can be as simple as a microstrip patch fabricated on one side of a circuit laminate with a slightly larger ground plane underneath it, on the other side of a dielectric layer. The low profile of such antennas makes them attractive for mounting within systems that have any available flat surface.

RF/microwave PCB Antennas


RF/microwave PCB antennas can be fabricated with many different transmission-line technologies, such as stripline and coplanar-waveguide transmission lines. They may even combine several different transmission lines within the same PCB antenna design.

Low-profile Flexible PCB Antenna

The RoHS-compliant antenna is designed for use with "Penta-band" frequencies, which include AMPS from 824 to 896 MHz, GSM from 880 to 960 MHz, DCS from 1710 to 1880 MHz, PCS from 1850 to 1990 MHz, and UMTS from 1710 to 2170 MHz. The compact 50-Ω antenna measures 41 × 24 mm with linear polarization and an omnidirectional radiation pattern.

Low-profile PCB Antenna


low-profile PCB antenna assembly can support a wide range of frequencies covering a total range of 824 through 2170 MHz.

A growing trend in the design of PCB antennas is multiple-frequency-band coverage to accommodate systems with wideband frequency ranges and/or multiple applications.

Difference between Ceramic Antenna and PCB Antenna and IPEX Antenna


Ceramic antenna is a miniaturized antenna suitable for Bluetooth devices.

Ceramic antenna is divided into block ceramic antenna and multi-layer ceramic antenna.


Ceramic antenna


Ceramic Antenna

Block antenna is to use high temperature to sinter the whole ceramic body once and then print the metal part of the antenna on the surface of the ceramic block.

The multi-layer antenna is sintered at high temperature after laminating and aligning the multi-layer ceramics by low temperature co-firing. So the metal conductor of the antenna can be printed on each layer of ceramics dielectric layer according to the design requirements, which can effectively reduce the size of the antenna and achieve the purpose of concealing the antenna.

Because the dielectric constant of ceramic is higher than that of PCB circuit board, the size of antenna can be reduced effectively by using ceramic antenna.

PCB antenna refers to the part of PCB used for wireless reception and transmission.


PCB antenna


PCB antenna

When transmitting, it converts the high frequency current of transmitter into space electromagnetic wave; when receiving, it converts the electromagnetic wave obtained from space into high frequency current input receiver.

Its advantages are: less space occupation, low cost, no need to assemble antenna alone, not easy to touch damage, easy assembly of the whole unit, but at a cost - Performance sacrifice.

The disadvantage is: single antenna field is difficult to achieve roundness, high insertion loss, relatively low efficiency, easy to be disturbed by the motherboard.

IPEX antenna is a kind of interface between RF circuit and antenna, which is widely used in the veneer of WLAN related products.


IPEX antenna


IPEX antenna

Its advantages are: better field control, low insertion loss, good directional direction of signal, high efficiency, strong anti-interference ability, can reduce interference by the motherboard, and do not need too much debugging matching, as a terminal manufacturer, only need to connect an IPEX antenna outside.

Of course, there are drawbacks: higher costs, assembly is more troublesome.
