Planar beam-forming array for broadband communication in the 60 GHz band

Abstract

A planar beam-forming antenna array is proposed that operates in the 60 GHz frequency band.The ar- ray consists of 6 balanced-fed aperture-coupled patch antenna elements [2] that are placed in a circular con- figuration.The resulting array has a maximum gain of 14 dBi and a 3 dB scan range of ±50 degrees.To demonstrate the performance, test arrays have been implemented with accompanying feed networks that apply the appropriate phase distribution over the ar- ray for beam-forming at several specific scan angles.Measurements validate the proposed array configuration.
