Product Description


Built-in Active Ceramic GPS BD 18*18MM Antenna With UFL/PEX For GPS Navigation


Ceramic antenna has four important parameters: gain, VSWR, noise figure and axial ratio. Especially the axis ratio, which is an important index to measure the difference of signal gain in different directions.

Ceramic antenna is another kind of miniaturized antenna suitable for Bluetooth devices. The types of ceramic antenna are divided into block ceramic antenna and multilayer ceramic antenna. Block antenna uses high temperature to sinter the whole ceramic body at one time, and then prints the metal part of the antenna on the surface of the ceramic block.

The multilayer antenna is fired in the way of low temperature co firing. The multilayer ceramic is laminated and aligned, and then sintered at high temperature. Therefore, the metal conductor of the antenna can be printed on each layer of ceramic dielectric layer according to the design requirements. In this way, the antenna size can be effectively reduced, and the purpose of hiding the antenna can be achieved. Because the dielectric constant of ceramic is higher than that of PCB, ceramic antenna can reduce the size of antenna effectively

Ceramic antenna is made of ceramic and weighs only 200g. Its frequency range is between 902mhz and 928mhz. Moreover, the dielectric loss of ceramic is smaller than that of PCB, so it is very suitable for Bluetooth module with low power consumption. The effect of ceramic antenna is better than that of on-board antenna. Generally, it has ant access pin and anchor, so it is very convenient to use.

The ceramics of ceramic antenna are used in radio. In addition to capacitors, there is also a device called ceramic filter (because it is connected to the antenna circuit, many people mistakenly think it is an antenna). It is made of lead zirconate titanate ceramic material. The ceramic material is made into flakes, and both sides are coated with silver as electrodes. After DC high voltage polarization, it has piezoelectric effect. It plays the role of filtering and has the characteristics of stability and good anti-interference performance.

Ceramic antenna has four important parameters: gain, VSWR, noise figure and axial ratio. Especially the axis ratio, which is an important index to measure the difference of signal gain in different directions.

The working principle of ceramic antenna is to use GPS satellite to achieve navigation and positioning, and the main task of the user's receiver is to extract the pseudo-random noise code and data code in the satellite signal to further calculate the position, speed and time (PVT) and other navigation information of the receiver carrier. The principle of ceramic antenna is divided into two parts: one is the transmitting antenna, the other is the receiving antenna.

Working principle of ceramic antenna

Ceramic antenna transmitting antenna is to transform the high-frequency electric field formed between the antenna and the ground into electromagnetic wave through an electrode called "antenna", so that it can be transmitted to the distance.

The receiving antenna of ceramic antenna simply means that the electromagnetic wave from the air is induced into electric field by an electrode called "antenna", which generates high-frequency signal voltage and sends it to the receiver for signal processing.

The above is the working principle of the ceramic antenna. In the design of the ceramic antenna unit, a high-frequency and low-noise amplifier is used to reduce the thermal noise of the antenna and the influence of the previous unit circuits on the performance of the receiver. The function of the ceramic antenna is to transform the electromagnetic wave energy of the radio signal from the satellite into the current that can be absorbed by the electronic devices of the receiver, so the size of the antenna is small And shape are very important, because these can determine the ability of ceramic antenna to obtain weak GPS signal.
