Additional info for Antennas for Base Stations in Wireless Communications
One antenna is used for both transmitting and receiving. ■ Signals at more than one frequency are transmitted. Base stations normally have this entire feature set. Base stations, therefore, suffer from passive intermodulation (PIM). High-power signals excite the antenna of the base station, and intermodulation components cause back reflection to the receiver due to the antenna’s PIM. Since the receiver is highly sensitive and is able to sense very weak signals, the intermodulation signals cause interference.
