A Concentric Multiband Patch Antenna for Wireless Coordination in Coherent Distributed Arrays

Abstract

A multiband patch antenna designed for joint internode coordination and distributed array operation is presented. The antenna has three resonances, one in the L-band (1.880 GHz) enabling distributed array operation, and two in the X-band (9.539 GHz and 10.580 GHz) enabling inter-node coordination. These two frequency bands are addressed by two collocated patch antennas; a slotted patch antenna for the high frequencies surrounded by a larger patch that is used for the lower frequencies. Measured results of the antenna design demonstrate good radiation performance at each resonance.
