Abstract:
A patch antenna (600) includes a capacitive radiating patch (604), a ground plane (502), and vertical coupling elements (630) electrically connected to defined portions of the capacitive radiating patch and the ground plane. The capacitive radiating patch includes an array of conductive segments (660, 662, 664, 666, 670) along the periphery and within the interior of the capacitive radiating patch. Capacitors (640) are electrically connected to specific conductive segments in a defined pattern. Vertical coupling elements electrically connect specific conductive segments along the periphery of the capacitive radiating patch to the ground plane. Vertical coupling elements can be conductors or defined combinations of resistors, inductors, and capacitors. Various embodiments of the patch antenna are configured for linear polarization and circular polarization.
