Document Type and Number:
WIPO Patent Application WO/2022/108355
Kind Code:
A1
Abstract:
The present invention may provide a base station antenna comprising: a plurality of antenna elements; a phase shifter for adjusting a beam tilt formed by the plurality of antenna elements; an RET module, inserted into the base station at a predetermined position , which receives a combined signal and separates the combined signal into a DC power signal to be supplied to at least one motor for adjusting the phase of the phase shifter and a control signal for controlling the at least one motor so as to drive the motor; and at least one bias tee module which receives an integrated signal from a base station body, separates the integrated signal into a combined signal and an RF signal, and transmits the separated combined signal to the RET module, wherein, when the RET module is inserted into the base station at the predetermined position, the at least one bias tee module is coupled with at least one bias tee coupling connector protruding from a predetermined position on a side of the RET module such that an RET coupling connector for transmitting the combined signal separated from the integrated signal to the RET module is formed so as to protrude on a predetermined position on the side.
