Abstract: This invention discloses a design and implementation of an X-band antenna optimized for a moving vehicle to communicate with a stationary orbit satellite. The new antenna design employs unique circuit boards that contain dipole elements, power dividers, pin diode switches and digital phase shifters. The circuit boards perform together as an array to produce high gain beams. Depending on the antenna performance needs, several antenna boards may be required. The circuit boards' dimensions are all identical containing round disks of equal diameters. The dipole radiating elements are located near the outer edge of the board. They are designed to perform circular type polarization. By increasing the diameter of the board and a number of boards, or a combination of the two, one can achieve any desired beam shape that may be required. The disclosure design approach is unique and flexible; for this reason, an eight circuit board vehicle antenna has been configured.

Abstract: This invention discloses a design and application of a variable beam antenna optimized for WI-HI application in data, video and voice transmission between various systems with an emphasis on medical monitoring. The subject antenna consists of a unique group of dipole radiators that are excited by zigzag feed lines and perform together as an array. This antenna is unique because it can provide various high gain beams by simply applying electrical shorts at the cross points in the feed lines. The shorts can be created mechanically or electronically. The antenna beam coverage can range from 15° to 110°- wide in H plane and maintains a constant beam width of 60° in E plane. The shorts are applied to reduce the antenna effective aperture, thereby increasing the beam width of the antenna. The current that flows to the outer dipoles are cut-off due to the shorts.

Abstract: A high performance broadband antenna for backpack and helmet application allowing data, video, and voice transmission between parties. The antenna consists of a pair of triangle shaped elements which are configured to stick on a backpack surface or place over a helmet with a coaxial cable connecting a radiating structure to the communication equipment on the body. A metal shielding performs as a ground plane and also acts as a protectant from radiation hazards to the head or body areas. The antenna is made with materials that conform to the shape of a helmet or stick directly onto a backpack surface. This design can function under multiple frequencies on UHF and S bands; its placement on a helmet receives less Interference from Its surroundings.

The subject antenna consists of a pair of triangle shape elements which are configured to stick on a backpack surface or place over a helmet with a coaxial cable connecting the radiating structure to the communication equipment on the body. A metal shielding surface is employed and the shielding surface performs as a ground Wane and also acts as a protectant from radiation hazards to the head or body areas. The antenna is made with materials that are accommodating and can easily conform to the shape of a helmet or sticking directly onto the backpack surface. This innovative design can function under multiple frequencies on UHF and S bands; its placement on a helmet receives less interference from its surroundings.
