Since the satellite is located in a high-altitude orbit, the signal reaching the ground is weak. Therefore, after the signal is received by the antenna, it needs to go through the shortest possible path to reach the input port of the receiver's low-noise amplifier. Therefore, placing the low-noise amplifier directly on the back of the antenna is a better solution for achieving system performance. Therefore, the Beidou antenna has become an important part of the navigation receiving system. So what is the Beidou antenna? What are its characteristics? The following professionals from Aris Technology will analyze it for you:
Overview of Beidou Antenna:
Beidou antenna is a bidirectional system with both positioning and communication. Beidou not only solves the problem of where I am, but also solves the problem of where he is when you are here. Beidou's user terminal actually has transceiver functions, while Beidou has transceiver functions. Its positioning needs to be transmitted and then the position is obtained. At the same time, its position may be transmitted to you and to people who care about you. In fact, Beidou antenna is a device with dual functions of positioning and communication. It is different in user groups and receiving occasions. But there is a capacity limit.
Features of Beidou Antenna:
High reliability, high sensitivity, strong anti-interference ability, suitable for long-term use in the field of timing.
Cable interface: default N-type connector (recommended), optional BNC, TNC, etc.
Cable length: 30 meters, 50, 80 and other cables of different lengths can be customized.
The above is the introduction of Beidou antenna. At present, most Beidou antennas are right-hand polarized ceramic dielectrics, and their components are: ceramic antenna, low-noise signal module, cable, and connector. Among them, ceramic antenna is also called passive antenna, dielectric antenna, PATCH, which is the core technology of Beidou antenna. The signal receiving ability of a Beidou antenna depends largely on the composition of its ceramic part.
