Abstract: An adjustable antenna baffling system includes a mounting plate for antenna radiating elements, baffles, connecting links that connect the baffles to the mounting plate, limit brackets that limit movement of the connecting links, an actuator and a housing. Pushing or pulling a handle on the actuator rotates the connecting links and extends or retracts the baffles to adjust the beamwidth. The housing encloses the components of the system except the handle and a lock tab on the mounting plate. The handle is secured to the lock tab to lock the baffles in the selected position.

Abstract: A circuit board mounting system has a mounting plate and standoffs. The mounting plate has several parallel slits. The standoffs have a base with an elongated slot and an upright post. Fasteners through the slot mount the standoffs anywhere along the slits. The standoffs can rotate around the fasteners and translate relative to the fasteners before the fasteners are tightened, so that a post can be located anywhere on the mounting plate. Circuit boards are mounted to the tops of the standoff posts.

Abstract: A transition for connecting a coaxial cable to a conductive metal part such as an antenna has a base and a sleeve. According to the method of the present invention the base is pressed into the groundplane of the antenna to provide a permanent conductive and mechanical connection. A low profile transition has a base and a channel portion parallel to the face of the base.

Abstract: An enclosure system for a radio board and an antenna circuit has a downwardly opening, concave housing with a interior housing cavity, a base that fits across the bottom of the housing, and a mounting plate that mounts on the base and extends into the housing cavity. The radio board and antenna mount on the mounting plate. A transparent cable access door has spaced knockouts that allow routing of communication interface cables. Mounting bolts attached to the exterior of the housing allow mounting of a mounting bracket. The bottom of the base is flat for placement on a flat surface.

Abstract: An omnidirectional dual band antenna system includes a radome and an antenna in the radome. The antenna has a linear array of lower frequency band driven elements, a linear array of higher frequency band driven elements and a linear array of parasitic elements, spaced in parallel planes with the array of higher frequency band driven elements in the middle. The parasitic elements couple to the higher frequency band driven elements and reshape the radiation pattern of the higher frequency band driven elements to correct for distortion caused by the lower frequency band driven elements.

Abstract: A microstrip fed log periodic antenna has two spaced dipole strips mounted on a ground plane. Each dipole strip has a trunk with a base, tip and alternating arms extending perpendicular to the trunk. One dipole strip includes an integral transmission feed line that extends from the tip, along the trunk of the other dipole strip at constant distance and along the ground plane at a constant distance. The one piece dipole strip with the integral transmission feed line reduces passive intermodulation and simplifies manufacture.

Abstract: An antenna system includes a ground plane, an aperture array of patch radiating elements and a feed structure. The feed structure has a first and second beam forming networks that each couple to selected radiating elements to form first and second antenna arrays. At least one and less than all of the radiating elements are shared by the first and second antenna arrays.

Abstract: Ultra-broadband thin planar antenna has a flat elliptical element and a spaced rectangular element co-planar with the elliptical element. The inner conductor of a coaxial cable connects to the elliptical element near a gap between the elements and the outer conductor of the coaxial cable connects to the rectangular element. A housing encases the elliptical and rectangular elements and the transmission line. The antenna functions electrically as an asymmetrical planar dipole having a special configuration or as an elliptical planar monopole with a co-planar finite rectangular ground plane.

Abstract: A microstrip patch radiator has parallel conductive strips that are connected at opposite ends by conductive connecting strips and separated by slits. The slits are parallel to the direction of the desired patch currents, and perpendicular to the undesired currents, to provide a low impedance path for currents generating the desired antenna polarization, and a high impedance path for orthogonal currents generating the undesired, cross-polarized radiation of the patch.
