What is the difference between Ceramic Antenna and PCB Antenna?

1. Ceramic Antenna:Ceramic Antenna's space design is smaller, better performance; narrower carrier band, more difficult to realize multi-band; so to improve the mainboard’s integration can reduce the antenna’s ID limitations; but this is to be planned at the beginning of the mainboard design.

   Block Antenna:The entire ceramic body is sintered at high temperature in a single pass and then the metal part of the antenna is branded on the surface of the ceramic block.

   Multi-layer Antenna:Sintering mainly using low temperature co-firing method to make multi-layer ceramic stacked in turn and then high temperature layer by layer sintering, the internal structure of all the antenna's conductor metal can be printed according to the design requirements of each layer of ceramic dielectric layer on the final formation of a three-dimensional three-dimensional circuit boards, so you can effectively reduce the size of the antenna, and to achieve the purpose of the hidden antenna to enhance the aesthetics and so on.Due to the pcb circuit board itself than ceramic dielectric coefficient is much lower, so the use of ceramic antenna can ensure that the antenna performance under the premise of effective work and then reduce the size of the antenna.

2. PCB Antenna:It refers to the wireless transceiver part on the PCB antenna. When transmitting, the wireless transceiver part firstly converts the UHF high-frequency current of the transmitter into electromagnetic wave in space; when receiving is completed, it converts the electromagnetic wave signal captured in space into high-frequency current and finally sends it to the corresponding receiver.

3. In conclusion: PCB antenna advantages and disadvantages analysis:Advantages: low cost, less space use area, no need to assemble antenna, touch free, easy to disassemble; Disadvantages are: a single antenna field is difficult to achieve roundness, high insertion and extraction loss, low efficiency, and more subject to external interference factors.
