Abstract

A six-beam-switched array antenna witha flat profile was designed for the application of high-speed wirelesslocal-area networks in the range of 5–6 GHz. This six-beam-switchedarrayantenna is composed of an analog beamformer and a microstrip-slot array. Thebeamformer, including single-pole double-throw switches, quadrature couplers,and power splitters, was implemented on a single substrate, while the arraywas designed with three pairs of microstrip slots for the ease of integrationwith the beamformer as a low-profile two-layer structure. The circuitsimulator and the full-wave numerical electromagnetic simulator were employedfor circuit and antenna design to generate six spatially oriented antennabeams. Measurement of the six-beam-switched antenna was also conductedand showed the accurate generation of six switchable antenna beams.
