Dual-fed antenna includes a ground plane; first and second metal patch radiators positioned over the ground plane, the first and second metal patch radiators are mirror images of each other; the first and second metal patch radiators separated by a meander-shaped gap, thereby forming an interdigitated structure, with each radiator having at least three digits; each digit shorted to the ground plane using a corresponding metal pin; each radiator having a coaxial feed implemented as a connector connected to it through the ground plane, or an aperture-coupled feed. Matching networks can be connected to the coaxial feeds at both ports or to microstrip lines connected to the slots of the aperture-coupled feeds. Each radiator can have tuning pins on an opposite side of the radiator from the digits, where each tuning pin can have a capacitive load. A dielectric plate can be placed between the radiators and the ground plane.
