Abstract

Design of circularly polarized active antennas of dual-fed square patch type is given, and spatial power combining and phased array operation of the antennas have been successfully achieved. In a phased array experiment of the arrays with two and three active antennas by the method of varying their free-running oscillation frequencies, we obtained the scan angles from -12° to +13° and those from -13° to +13°, respectively, and good axial ratios together with high spatial power-combining efficiencies.
