Differences between ceramic antenna, PCB antenna and IPEX antenna

1、 Ceramic small antenna

Ceramic small antenna is a miniaturized antenna suitable for Bluetooth devices. Now let's introduce the differences between these three antennas.

Ceramic small antenna is divided into block ceramic small antenna and multilayer ceramic small antenna.

The block small antenna uses high temperature to sinter the whole ceramic body at one time, and then print the metal part of the small antenna on the surface of the ceramic block.

The multi-layer small antenna is fired by low-temperature CO firing to stack and align the multi-layer ceramics, and then sintered at high temperature. Therefore, the metal conductor of the small antenna can be printed on each ceramic dielectric layer according to the design needs. In this way, the size of the antenna can be effectively reduced and the purpose of hiding the small antenna can be achieved.

Because the dielectric constant of ceramic is higher than that of PCB, the use of ceramic small antenna can effectively reduce the size of antenna.

2、 Advantages of PCB antenna

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

When transmitting, PCB antenna converts the high-frequency current of the transmitter into space electromagnetic wave; When receiving, the PCB antenna converts the electromagnetic wave obtained from space into high-frequency current and inputs it to the receiver.

The advantages of PCB antenna are: the PCB antenna occupies less space and has low cost. There is no need to assemble the antenna separately. The PCB antenna is not easy to touch and damage. The whole PCB antenna is easy to assemble, but there is a price - the performance of the PCB antenna is sacrificed.

The disadvantages of PCB antenna are: it is difficult to round the field type of a single antenna, the slot of PCB antenna is improved, the efficiency is relatively low, and it is easy to be disturbed by the main board of PCB antenna.

3、 Advantages of IPEX small antenna

IPEX small antenna is a kind of interface between RF circuit and antenna, which is widely used in wireless local area network (WLAN) related products.

The advantages of IPEX small antenna are: the field type of IPEX small antenna can be controlled better, the insertion loss is low, and the directional directivity of the signal is good. IPEX small antenna has high efficiency and strong anti-interference ability. IPEX small antenna can reduce the interference from the main board without too much debugging and matching. As a terminal manufacturer, it only needs to connect an IPEX small antenna outside.

Of course, IPEX small antenna also has disadvantages: the cost is high, and the assembly of IPEX small antenna is more troublesome.
