Abstract
A method and apparatus for sharing antennas between bases stations that is non-band limiting. A transmit signal is received at a first port coupled to a base station. The transmit signal travels from the first port through a plurality of circulators prior to being transmitted by an antenna. A received signal is received at a second port that is communicatively coupled to the antenna. The received signal conceptually travels through the apparatus in a reverse direction to the transmit signal, through at least one of the circulator units, and is admitted to the base station using at least the same port that received the transmit signal. The signal may be split, and also received by a different base station.
