The growing demand for higher data rates imposes special requirements for broadband, beam switching and dual-polarization mode for telecommunications antennas. In this paper, we present a design of 16-element planar patch antenna array with a Butler matrix feed network for the frequency range of 26-31.4 GHz. The antenna array operates with two linear orthogonal polarizations and provides ±42º beam switching. The Butler matrix is based on a novel combination of wideband planar couplers, crossovers and phase shifters. The design is fabricated on a low-cost multi-layer board. Experimental measurements of return loss, mutual coupling and radiation patterns confirm the wideband operational mode and wide-angle beam switching.
