摘要： An antenna array that uses at least two passive antennas and one active antenna disposed above a ground plane, but electrically isolated from the ground plane, and a respective resonant strip positioned beneath each passive antenna. The passive antenna elements are positioned about the active element, and each of the at least two passive antenna elements is individually set to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus.

摘要： An antenna array formed on a deformable dielectric material or substrate includes a center element and plurality of radial elements extending from a center hub. In the operative mode, the radial elements are folded upwardly into an approximately vertical position, with the center element at the center of the hub and the radial elements circumferentially surrounding the center element. In one embodiment the center element serves an active element of the antenna array and the radial elements are controllable in a directive or reflective state to effect a directive beam pattern from the antenna array. When not in use, the antenna elements are deformed into a plane and can therefore be integrated into a housing for compact storage. In a phased array embodiment, the center element is absent and the plurality of radial elements, are controllable to steer the antenna beam.

摘要： An antenna array having a central active element and a plurality of passive elements surrounding the active element is disclosed. A dielectric substrate or other slow wave structure is disposed radially outwardly from the passive elements for slowing the radio frequency waves so as to increase the antenna directivity by reducing the amount of energy radiated in the elevation direction.

摘要： A monopole antenna for use with a mobile subscriber unit in a wireless network communications system. The antenna includes a radiating element located near a feed point to minimize transmission delay from the feed point to the element, and a ground patch located above the element to force the beam peak down towards the horizon. The antenna is fabricated with printed circuit board (PCB) photo-etching techniques for precise control of the printed structure. The monopole antenna includes a planar substrate made of dielectric material. A conductive planar element is layered on one side of the substrate, and a conductive planar ground patch is layered on the other side of the substrate. The conductive planar element is located in a lower region of the substrate, while the location of the conductive planar ground patch is offset from the conductive planar element in an upper region of the substrate, that is, the ground patch is stacked above the conductive planar element. The feed point is typically connected to a transmission line for transmitting signals to and receiving signals from the antenna. A strip is connected to the conductive planar ground patch and extends from the patch to a bottom edge of the substrate for coupling the ground patch to a ground plane upon which the antenna is mounted.
