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: Base station antennas (BSAs) include at least one feed signal phase shifter having a variable length signal path therein, which provides an adjustable signal delay in response to mechanical actuation thereof. A thermo-electric actuator is provided to support remote electrical tilt operations by mechanically actuating the variable length signal path in response to an actuator drive signal. The thermo-electric actuator may include thermally-deformable components, such as SMA springs and wax motors.

Abstract: A MIMO antenna system includes a pair of vertical monopole radiating elements on a forward-facing surface of a substrate, and first and second arrays of horizontal dipole radiating elements, which are arranged as a closed-loop of radiating elements on a rear-facing surface of the substrate. Each radiating arm of each of the horizontal dipole radiating elements in the first and second arrays is electrically coupled by a respective horizontal feed stalk to edges of a ground plane, which is provided on the rear-facing surface of the substrate. First and second feed signal routing networks are provided on the forward-facing surface of the substrate, and are electrically coupled via the substrate to the first and second arrays of radiating elements, respectively.

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.
