Abstract :
To achieve dual-polarized switched beam antenna, this paper proposes an orthogonal patch array with analog phase shifter. The proposed antenna is used for an indoor base station antenna of LTE. Its feeding circuit consists of a pair of analog phase shifters using varactor diodes to control the output phase independently. A prototype antenna provides dual polarized ±15° beam switching in both E and H planes.
