Abstract: Beam forming antennas for base station applications are configured as dielectric resonator antennas (DRAs) having arrays of dielectric resonator radiating elements (DRRE) therein with dual-polarized radiating properties. Each DRRE includes a dielectric radiating element (DRE) electromagnetically coupled by a resonant cavity to a respective cross-polarized feed network, which is responsive to first and second radio frequency (RF) input feed signals. Each resonant cavity may be configured as a polymer-filled resonant cavity, and each DRE may be configured as a cylindrically-shaped or dome-shaped dielectric radiating element.

Abstract: An antenna includes a cross-polarized feed signal network configured to convert first and second radio frequency (RF) input feed signals to first and second pairs of cross-polarized feed signals at respective first and second pairs of feed signal output ports. A feed signal pedestal is provided, which is electrically coupled to the first and second pairs of feed signal output ports, and a patch radiating element is provided, which is electrically coupled by the feed signal pedestal to the first and second pairs of feed signal output ports. This patch radiating element may be capacitively coupled to first and second pairs of feed signal lines on the feed signal pedestal, which are electrically connected to the first and second pairs of feed signal output ports.
