Abstract: The system contains an antenna feed. A signal is in communication with the antenna feed. The signal has a wavelength and a period. A signal lens has a periphery portion that is thicker than an interior portion, wherein the signal propagates through the signal lens. The signal lens is designed such that the signal propagates through the periphery portion of the signal lens approximately one wavelength slower than through the interior portion of the signal lens.

Abstract: An antenna for providing radiation pattern control contains an antenna housing having a plurality of reflective wings and at least one linear element located above the reflective wings. The antenna also contains a radiation element situated within the antenna housing so as to allow the antenna housing to control a pattern of radiation emitted by the radiation element.

At least one feed is provided at least partially within the enclosure.

Abstract: The quasi-twin lead line includes a dielectric substrate having a first side and an opposite side. A top conductor trace is integral with the first side of the dielectric substrate. The top conductor trace has a top conductor axis, a top conductor length, and a top conductor width, wherein the top conductor width is substantially uniform along the top conductor length. An opposite trace is integral with the opposite side of the dielectric substrate. The opposite trace has an opposite length and an opposite width substantially congruent to the top conductor length and the top conductor width. The opposite trace also has an opposite axis substantially parallel to the top conductor axis, wherein a plane containing both the top conductor axis and the opposite axis is oblique relative to the dielectric substrate.

Abstract: An omnidirectional antenna and method of producing the omnidirectional antenna is provided. Generally, the antenna has a first board with a ground plane on a first side of the first board and a second board with one or more dipole antennas located next to a first edge of the second board and one or more dipole antennas located next to a second edge opposite the first edge.

Abstract: A device and method for patch antenna with enhanced feed is provided. Generally, the patch antenna comprising: a ground plate, a patch plate parallel to the ground plate, a shorting wall, and a feed line. The shorting wall connects an edge of the ground plate to an edge of the patch plate. The feed line passes through an aperture in the ground plate and connects to two locations on the patch plate.

Abstract: An assembly for providing a weatherproof feedthrough for data communications cables into a structure. The assembly includes a unique housing having a cavity for removably receiving a connector attached to a terminal end of a cable in a fixed orientation. The cable attached to the connector in the cavity exits the assembly into a protected side of the structure. A cable from the unprotected side of the structure enters the assembly such that a connector disposed on its terminal end may be connected to the connector in the cavity. The assembly is particularly suited to allow off the shelf connectors to be used within the housing. The assembly may include strain relief devices for protecting the cables attached to the connectors.

Abstract: An antenna feed with an integrated bandpass filter is disclosed. The antenna feed contains a reflector and a dipole antenna. A bandpass filter comprising one or more bandpass filter elements is placed between the reflector and the dipole antenna. The bandpass filter elements may be configured as traces on a printed circuit board. The printed circuit board may also contain the dipole antenna. Integrating a bandpass filter with the dipole antenna results in bandpass filtering with a small insertion loss and low cost.

Abstract: A multi-element directional antenna and process for making same are described. The antenna comprises a lightweight dielectric substrate having an array of parasitic elements disposed on the substrate. A printed circuit board having a ground plane on one side thereof, and a driven element and phasing means comprising a hybrid (magic-or-twin) tee junction on the other side thereof, disposed coplanar with the parasitic elements and the substrate. The multi-element directional antenna, may be formed using low labor cost manufacturing process such as stamping and laminating, and additive and/or subtractive (i.e. etching) techniques.
