摘要： A very inexpensive and on-site tunable design for a vertically polarized panel antenna system, suitable for the FCC digital broadcast 700 MHz range is provided. Bowtie-like shaped antennas having machine-stampable planar elements with an adjustable separation are configured with a stripline feed. The stipline feed enables easy feeding of doublet systems to allow the configuration of an array of vertically polarized antennas. The various components of the antenna system can be easily tuned, enabling rapid deployment and quick operation.

摘要： A monitoring system for an transmission line, such as a multi-channel television broadcasting antenna feed line, gathers data about the physical and electrical condition of the line in real time. The system can detect and localize deterioration and other time-dependent faults in the transmission line by the tendency of faults to produce reflections back to the transmitter that were not part of the original characterization of a particular installation. Some kinds of faults, identified early enough, can be corrected without replacing components, and especially without shutting down the transmission line during prime viewing hours. Other faults can be detected in time to order replacement parts before the underlying problem becomes severe, and to allow servicing during periods of low demand.

摘要： A bow-tie slot panel antenna is described, having a parasitic element positioned at an orientation from the slot to generate orthogonal fields. By adjusting the coupling ratios, dimensions and angle of orientation of the parasitic element, circularly polarized fields can be effectively produced, using the panel antenna as the primary radiator.

摘要： A dual-port corporate-feed broadband antenna uses two pairs of crossed dipoles in each bay, fed by a single hybrid coupler in each bay, to support hybrid-mode IBOC® VHF-band broadcasting. Each 3 dB quarter-wave coupler receives a share of an analog FM broadcast signal on a first input and a digital OFDM broadcast signal, 20 dB down, on a second input. The respective coupler output ports drive coaxial lines to tees feeding respective quarter-wave-separated crossed dipoles. The dipoles in each bay are arranged in a square to one side of their coupler, making side mounting practical. The resultant omnidirectional analog and digital radiation patterns have the same circular polarization and opposite phase rotation. Bay spacing for vertical null is a function ((n−1)/n) of the number of bays in the antenna.

摘要： A circularly polarized patch antenna uses a square quarter-wavelength conductive plate, spaced away from a slightly larger backing conductor. Excitation uses a coaxial feed stem pair, whereof respective inner conductors join the patch at orthogonal locations on a reference circle, and outer conductors intrude past points of joining to the backing conductor to establish gaps that interact with patch and backing conductor size and spacing to jointly establish terminal impedance. A parasitic element in the propagation path broadens bandwidth, while a frame behind serves to define a cavity reflector. A power divider behind the frame converts a single applied broadcast signal into two equal signals with orthogonal phase, which signals are delivered to the feed stems with equal-length coaxial lines.
