| 20110053648 | Wireless Point to Multipoint System - A patch array antenna includes a base on which is defined a ground plane. A plurality of first patch elements are configured to resonate over a frequency range. Each patch element is isolated from the ground plane and disposed on the base over the ground plane so that an air dielectric is defined between the patch element and the ground plane. A plurality of parasitic second patch elements are disposed on the second base so that the second patch elements face the first patch elements across an air filled gap. | 03-03-2011 |
