SELF-DIPLEXING ANTENNA FOR IMPROVED TX/RX AND ANTENNA ISOLATION

摘要

A self-diplexing antenna for improving transceiving separation and antenna separation properties is provided to enable plural radiation elements to be orthogonal together, and to pass the elements through a 180 degree power distributor /synthesizer, thereby improving separation of transceiving paths. A donor antenna unit(210) consists of the first to fourth radiation elements or terminals. A donor power distributor/synthesizer forms a downlink RF(Radio Frequency) signal and an uplink RF signal as two signals of the same size. An amplifier amplifies the downlink RF signal and the uplink RF signal into predetermined gains, respectively. A service power distributor/synthesizer forms the amplified downlink and uplink RF signals as two signals of the same size. A service antenna unit(310) consists of the first to fourth radiation elements or terminals to send the downlink RF signal as receiving the uplink RF signal.
