COMPACT SINGLE FEED DUAL-POLARIZED DUAL-FREQUENCY BAND MICROSTRIP ANTENNA ARRAY

摘要

A dual-polarized stacked patch antenna array that operates at twodifferent frequencies. The stacked patch antenna array has a single planarpatch antenna subarray disposed on opposite sides of a dielectric structure.The stacked patch antenna array includes a ground plane that is common toeach planar patch array antenna. Each planar patch antenna subarray is fedfrom a single coaxial probe disposed through the center of the stackedantenna array structure. Each patch in the planar patch array antennasubarray is electrically connected by microstrip elements. Each patch andmicrostrip element is arranged along the X and Y axial directions. A singleadditional microstrip element is placed in a diagonal orientation in eachsubarray to connect two patches oppositely oriented within the stackedantenna array structure.
