The basic principle of base station antenna

The basic principle of base station antenna It is the high frequency current in its surroundings to produce changing electric field and magnetic field, according to Maxwell electromagnetic field theory, "changing electric field produces magnetic field, changing magnetic field produces electric field", so that the continuous excitation goes on, it realizes the propagation of wireless signals, the specific working principle of the process is:

1. the core network side of the control signaling, voice calls or data service information sent to the base station through the transmission network (in the 2G, 3G network, the signal is first transmitted to the base station controller, and then transmitted to the base station).

2. The signal is processed by baseband and RF on the base station side, and then sent to the antenna for transmission through RF feeder.

3. The terminal receives the radio waves transmitted by the antenna through the wireless channel, and then demodulates its own signal.
