The difference between ceramic antenna and pcb antenna
2022.11.24
Nowadays, navigation antenna is more and more widely used in our life, such as mobile phones, electronic watches, cars, navigation equipment and so on. For different applications, navigation antennas can be divided into many types, such as built-in antenna, GPS antenna, external antenna, timing antenna and so on. So what is the difference between the common ceramic antenna and pcb antenna? Many people don't. Next, let Xiaobian explain it to you in detail
Ceramic antenna
It is a miniaturized antenna suitable for Bluetooth devices, which is divided into block ceramic antenna and multilayer ceramic antenna.
Ceramic antenna occupies small space, good performance; The band width is narrow, and it is difficult to realize multi-band; Effectively improve the integration of the motherboard, reduce the antenna to ID restrictions; It is necessary to import the design at the beginning of the motherboard definition.
Two classifications of ceramic antennas
Block antenna:
The entire ceramic body is sintered at high temperature, and then the metal part of the antenna is printed on the surface of the ceramic block.
Multi-layer antenna:
The multi-layer ceramics are aligned in layers by co-firing at low temperature and then sintered at high temperature. According to the design requirements, the metal conductor of the antenna can be printed on each ceramic dielectric layer to effectively reduce the size of the antenna and achieve the purpose of hiding the antenna.
Because the dielectric constant of ceramic is higher than that of pcb, the ceramic antenna can ensure the performance of antenna and reduce the antenna size effectively.
PCB antenna
A PCB antenna is the part of a PCB used for wireless transceiver. When transmitting, the high frequency current of the emitter is converted into space electromagnetic wave; When receiving, the electromagnetic wave intercepted from space is converted into a high-frequency current, which is finally sent to the receiver. The advantages of PCB antenna, occupy small space, low cost, do not need to assemble the antenna separately, the possibility of contact damage is small, the whole assembly is convenient.
That's the difference between a ceramic antenna and a pcb antenna. Now we all know, day about more antenna dry goods, welcome to comment area to discuss Oh.
