摘要： Systems, apparatuses and methods may provide for an antenna system including a cavity and a broadband antenna coupled to the cavity. The broadband antenna may include surfaces defining a slot, wherein a cross-section of the cavity defines a resonant frequency range of the slot. The broadband antenna may also include a plurality of transmission lines, wherein the plurality of transmission lines bridge the slot and are spaced apart at a sub-wavelength distance with respect to a target frequency range of the antenna system. Additionally, the broadband antenna may include a plurality of inductive tuning elements, each inductive tuning element being disposed adjacent to one of the plurality of transmission lines, wherein the target frequency range is a function of the resonant frequency range and an impedance associated with the plurality of inductive tuning elements.

摘要： A method is provided for designing an antenna comprising: i) determining dimensions of a fractional-mode, FM, air-filled, AF, antenna cavity, a FM-AF cavity, resonating around a target centre frequency characterized by a conductive ground cavity layer, a conductive top cavity layer, conductive cavity sidewalls between the top and ground cavity layer, and a side opening resulting from the fractional-mode; ii) adding a guard trace for shielding radiation from the side opening by adding sidewalls at a distance from the side opening; wherein the conductive top cavity layer is at least partially open over said distance thereby obtaining a radiating slot between the guard trace and the FM-AF cavity; wherein the FM-AF cavity and radiation slot forms an antenna cavity; iii) matching the impedance of the antenna cavity around the target centre frequency by adjusting the FM-AF and/or radiating slot dimensions within a maximum footprint.

摘要： 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.

摘要： In an antenna, a first antenna element includes a first radiation conductor and a first feeder line. A second antenna element includes a second radiation conductor and a second feeder line. A second feeder line is coupled to the first feeder line such that a first component, which is a capacitance component or an inductance component, is dominant. A first coupler couples the first and second feeder lines such that a second component different from the first component is dominant. The first and second radiation conductors are arranged at interval of ½ or less of resonance wavelength. The second feeder line is coupled to the first radiation conductor such that a third component, which is the capacitance component or the inductance component, is dominant. The first coupling portion couples the first radiation conductor and the second feeder line such that a fourth component different from the third component is dominant.
