ANTENNA WITH CONTROLLED SIDELOBE CHARACTERISTICS

摘要

An antenna with controlled sidelobe characteristics includes: a power coupler configured to receive a signal to be transmitted and generate and output a main channel signal and an auxiliary channel signal; a main channel power distributor configured to receive the outputted main channel signal and distribute power of the main channel signal; a main antenna configured to receive the power-distributed signal, the main antenna including a one-dimensional or two-dimensional array of a number of antenna elements; a vector signal controller configured to control amplitude and phase of the auxiliary channel signal; an auxiliary channel power distributor configured to receive the controlled amplitude and phase of the auxiliary channel signal and distribute power of the auxiliary channel signal; and an auxiliary antenna independently installed separate from the main antenna, the auxiliary antenna including an antenna element or an array of a number of antennas.
