Abstract: Antennas are provided herein that include a parasitic element that is coupled to an active element and a ground plane. In some embodiments, the active element is inside an outline provided by a combination of the parasitic element and the ground plane. Moreover, the active element and the parasitic element are, in some embodiments, on opposite surfaces, respectively, of a printed circuit board.

Abstract: A directional coupler includes a primary transmission line electrically coupled in series between an input port and an output port of the coupler, and an asymmetric, meander-shaped, secondary transmission line, which is electrically coupled in series between a coupling port and an isolation port of the coupler. The secondary transmission line includes a first coupling segment, which is reactively coupled to a first portion of the primary transmission line, and a second coupling segment, which is reactively coupled to a second portion of the primary transmission line, and is spaced closer to, or farther from, the primary transmission line relative to the first coupling segment, such that an asymmetry in reactive coupling is present between the first and second portions of the primary transmission line and the secondary transmission line. An intermediate segment is provided, which is electrically coupled in series between the first and second coupling segments. A coupling port segment is provided, which is electrically connected in series between the first coupling segment and the coupling port. And, an isolation port segment is provided, which is electrically connected in series between the second coupling segment and the isolation port.

Abstract: An antenna includes an elliptical waveguide having a plurality of length-tapered multi-slot arrays of elongate slots therein at respective spaced-apart locations along a length thereof. The plurality of length-tapered multi-slot arrays of elongate slots can include at least first and second length-tapered multi-slot arrays of elongate slots, which are spaced apart from each other along the length of the elliptical waveguide. The first length-tapered multi-slot array of elongate slots can include: (i) a first elongate slot having a first length and a first width, and (ii) a second elongate slot having a second length less than the first length and a second width that may be greater than the first width.

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.

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.
