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.

The plurality of flat radiator elements are interconnected along each inner edge and symmetrically arranged about a vertical axis centered on the ground plane hole. The electrical connector extends through the ground plane hole and is coupled to the radiator elements.

摘要： A dual-port IBOC® antenna provides omnidirectional radiation of orthogonal, circularly polarized analog (FM) and digital (OFDM) signals using quadruple coplanar square loops driven from a hybrid having balanced outputs. The loops are arranged in a tiled square, with proximal sides functioning as further stripline hybrids to cancel cross coupling between the loops. Each loop quad is reflector-backed and emits a directional signal; multiple loop quads oriented radially form an omni bay. Vertical spacing between bays includes a minimum position for mutual coupling, while symmetry establishes uniform input impedance on the hybrid input ports. Tuning barbs on the loops fine tune frequency response. Bandwidth is wide, so that a single antenna can radiate multiple FM analog and hybrid IBOC® channels over the VHF FM radio broadcast band.

摘要： A rebroadcasting apparatus for mobile media includes a receiving antenna and a transmitting antenna. The signal to be rebroadcast is received with a circularly polarized directional antenna. The transmitting antenna has circular polarization opposite to the polarization of the receiving antenna. Amplifiers and filters may be included between receiving and transmitting antennas to regulate retransmitted signal quality. The transmitting antenna uses one or more bays of quasi-helical dipole radiators excited using manifold feed equipped with tuning paddles. The transmitting antenna may be formed from light-weight sheet metal or other readily mass-produced materials. The transmitting antenna may be housed within an ordinary security camera enclosure or similar radio-transparent housing.
