Abstract: 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.

Abstract: An antenna system including an array of conductors connected to a feed line, wherein the array is configured to (1) emit electromagnetic radiation in response to an input signal being input to the array through the feed line or (2) output an output signal to the feed line in response to electromagnetic radiation being received on the array; and a director disposed in front of the array, wherein the director has a first reactive load having a complex impedance that is tailored to increase a directivity of the antenna system by reactively loading the conductors.

Abstract: A dynamically allocated broadband multi-tap antenna comprises a plurality of sub-wavelength conductors used for transmitting and/or receiving radio frequency (RF) signals; a plurality of antenna taps, each of which is connected to one or more of the conductors; a plurality of RF switches, each of which is connected to one of the antenna taps; and a plurality of combiners (which also function as splitters), each of which is connected to one or more of the RF switches. The RF switches are controlled to dynamically allocate and interconnect the antenna taps with a selected combiner, to communicate the RF signals between the conductors connected to the antenna taps and the selected combiner. The RF signals received by the conductors are combined into an output signal at the selected combiner, while an input signal at the selected combiner is split for transmission as the RF signals by the conductors.
