Stacked array antennas for high-speed wireless communication

摘要

Array antennas for wireless transmission having an array of emitters/receivers that are compactly arranged above an antenna feed and ground plate. These high gain devices may be configured to operate in any appropriate band, such as the 5.15 to 5.85 GHz band and/or the 2.40-2.48 GHz band. The antenna emitters are arranged in a separate plane (or planes) above an antenna feed connecting the emitting elements to the radio circuitry. The antenna feed is positioned between the emitters and a ground plane. The antenna array may be configured to operate with both horizontal and vertical polarization. The apparatuses may be configured for low impedance mismatch and may have a high gain relative to a very small and compact overall shape.

主权项

1. An array antenna comprising:
a ground plate in a first plane; a plurality of antenna radiating elements above the first plane wherein each antenna radiating element has a radiating surface extending in a plane above the first plane, wherein the antenna radiating elements may extend in the same plane or in different planes; a third plane between the first plane and the radiating surfaces; and a plurality of feed lines, wherein each feed line extends in the third plane between two or more of the antenna radiating elements to connect the two or more antenna radiating elements to each other, so that the plurality of radiating elements form a network that is fed by a common connection point; wherein the plurality of antenna radiating elements and the plurality of feed lines are part of a single continuous sheet of metal in which two or more edges of each antenna radiating element are connected through two or more slant feed lines to the plurality of feed lines in the third plane, further wherein the width of the slant feed lines narrows from the antenna radiating element to the plurality of feed lines.
