Abstract: The present disclosure describes dual-band antenna arrays and related methods for manufacturing and implementing dual-band antenna arrays. One exemplary dual-band antenna array comprises a top layer of fused silica substrate; a bottom layer of fused silica substrate; a ground plane positioned between the top and bottom layers of fused silica substrate, wherein the ground plane comprises layers of three different metals; antenna patch elements arranged on top of the top layer of fused silica substrate; an input feedline arrange on the bottom layer of the fused silica substrate; and a meanderline complimentary split ring resonator structure etched on a top surface of the ground plane, wherein the input feedline is directly coupled to the meanderline complimentary split ring resonator structure and is configured to excite a plurality of resonance frequencies of the antenna patch elements.

Abstract: The present disclosure describes various systems and apparatuses for a compact frequency reconfigurable array antenna and methods related thereto. An exemplary array antenna system comprises a substrate; an array of patch antennas positioned on the substrate; a plurality of PIN diodes placed on a top surface of the substrate, wherein individual PIN diodes are located in individual gaps between respective ones of the patch antennas; and a plurality of meander-line (ML) complementary split-ring resonator (CSRR) decouplers placed on a bottom surface of the substrate, wherein individual ML-CSRR decouplers are placed under individual patch antennas in a diagonal direction.
