    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： 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.

    摘要： An antenna array for use with a mobile subscriber unit in a wireless network communications system. The invention utilizes a multiplicity of resonant strips provided within the ground plane. These strips couple to an equal multiplicity of monopole array elements located on top of the ground plane. This approach increases antenna gain by more efficiently utilizing the available ground plane area. Additionally, since the active element is on top of the ground plane, the antenna array sensitivity is decreased because the direct coupling between the antenna and external environmental factors is minimized. The multiplicity of antenna elements are electrically isolated from the ground plane. Each antenna element has a bottom end located proximal to the ground plane, and is aligned along a respective antenna axis that is substantially perpendicular to the top side. Each resonant strip has a top end electrically connected to the ground plane and a bottom end spaced apart from a bottom side of the ground plane, and is aligned along the antenna axis of a corresponding antenna element. The multiplicity of antenna elements and the multiplicity of resonant strips are equally spaced about the perimeter of the ground plane, and the combination of each antenna element with a respective resonant strip provides a unbalanced dipole antenna element so that the multiplicity of dipole antenna elements form a composite beam which may be positionally directed along a horizon that is substantially parallel to the ground plane.

    摘要： An antenna array includes a dielectric substrate comprising an integral center hub including a pivotal center section therein, and a pivotal wings extending radially from the integral center hub. An active antenna element is on the pivotal center section of the integral center hub, and passive antenna elements are on the pivotal wings. The active antenna element and the passive antenna elements are pivotal between a stored position and an operational position. The active antenna element and the passive antenna elements are substantially planar when in the stored position, and are substantially perpendicular to the integral center hub when in the operational position.
