ANTENNA CONTROL SOLUTION AND ANTENNA ARRAY FOR INTERFERENCE CANCELLATION REPEATER

摘要

An antenna control method and antenna array for an interference cancellation repeater are provided to suppress interference signals by arranging the interference signal to a null area between antennas. A semi-spherical antenna attach jig(10) is processed to the angle of 60 degree in the form of antenna attaching. 9 low back lobe flat antennas(11) are adhered to the semi spherical jig to the angle of 60 degree. The flat antenna emits radiating beam to all donor directions. The radiation pattern of the electric wave radiated with the flat antenna has the angle of 60 degree around a main beam. The 9 low back lobe flat antennas receive the donor electric wave of all directions. The 9 antennas are adhered to an antenna switching semiconductor switch circuit. One of 9 antennas is selected as a switch control algorithm.
