Abstract

In this paper, we present a 60 GHz low-cost circularly polarized patch array antenna which exhibits excellent axial ratio performances. The 3 dB axial ratio bandwidth has been measured to be about 11.25%. The 10 dB return loss bandwidth is up to 17% while the gain is about 10.2 dBi at 60 GHz. These results have been obtained by applying a sequential feeding array to an aperture-coupled truncated corner patch. To the best knowledge of the authors, this work is the first report of a 60 GHz low-cost microstrip aperture-coupled patch antenna which presents such performances.
