Abstract: A fin-type planar antenna and a deployable dipole antenna are combined into a probabilistic system as a co-located orthogonal diversity fin antenna to reduce or eliminate cross polarization fades and cancellation dropouts common to wireless audio systems used in theaters, churches and convention centers over coaxial wired connections. Additionally, an optical line may connect the diversity fin antenna to a further circuit. The antenna system features broad bandwidth, resistance to deep nulls or fades caused by cross polarization, resistance to destructive interference, and an air space dielectric covering provides resistance to detuning in the presence of rain, or touching objects.

Abstract: A diversity antenna for receiving radio frequency (RF) signals includes a horizontally-polarized antenna element coupled to a vertically-polarized antenna element in a fixed orthogonal relationship. The vertically-polarized antenna element is a blade antenna which includes a vertically-oriented printed circuit board (PCB) on which is disposed a pair of conductive strips. The horizontally-polarized antenna element includes two loop antennas which are arranged and conductively coupled in parallel. Each loop antenna includes a horizontally-oriented, disc-shaped PCB on which is disposed a pair of conductive loops. To facilitate the orthogonal coupling between the pair of antenna elements, each disc-shaped PCB includes a central slot dimensioned to receive the vertically-oriented PCB.

Abstract: A radio frequency (RF) antenna assembly is mounted on a shielded panel to facilitate the transmission of RF signals therethrough. The RF antenna assembly includes an RF antenna formed from wire which is bent to define first and second antenna elements. The RF antenna is inserted through the panel with the first and second antenna elements disposed on opposite sides thereof. A dome-shaped cap constructed of a compressible elastomeric material is mounted over the first antenna element and lies flush against the outer surface of the panel. A disc-shaped dielectric base receives the distal end of the second antenna element and lies flush against the inner surface of the panel. The RF antenna exerts a spring-like force that resiliently draws the cap and base together. In use, each antenna element transmits RF signals within a designated frequency range to wireless electronic devices located on the same side of the panel.

Abstract: An antenna distribution unit distributes an input RF signal comprised of multiple discrete antenna feeds to a plurality of electronic devices in communication therewith. The antenna distribution unit engages in three-way signal splitting across a pair of successive splitting stages in order to produce an even multiplicity of high-quality signals across nine output ports. By limiting signal splitting to two splitting stages and carefully selecting components to maintain series and parallel impedance, a high-fidelity output signal is produced having an essentially flat spectrum over the target frequency band. In particular, the antenna distribution unit is optimized for use in the distribution of signals within the TV VHF low band of 50 MHz to 88 MHz, the TV VHF high band of 175 MHz to 213 MHz, the TV UHF band of 470 MHz to 610 MHz, and the 900 band of 900 MHz to 1000 MHz.

Abstract: Systems and methods are provided for analyzing radio frequency (RF) data. RF data is received from one or more RF sensors, wherein the RF data is collected over a particular frequency range and resolution bandwidth. One or more frequencies not in use are determined based on the RF data and a signal level threshold. One or more recommended frequencies for use are calculated based on the one or more open frequencies and an intermodulation function, wherein each of the one or more recommended frequencies reduces a potential for intermodulation distortion than other frequencies in the frequency range.

Abstract: A fin-type planar antenna and a deployable dipole antenna are combined into a system as a diversity fin antenna to reduce or eliminate cross polarization fades and dropouts common to wireless audio systems used in theatres, churches and convention centers. A dual feedline connects the diversity fin antenna system to a diversity-equipped receiver in a convenient and rapid manner. The antenna system features broad bandwidth, resistance to deep nulls or fades caused by cross polarization, and an air space dielectric covering provides resistance to detuning in the presence of rain, or touching objects.
