| 摘要 |
The present invention provides, among other things, antenna beam control devices, systems, architectures, and methods for radar and other applications, such as wireless communications, etc., to improve transmit and/or receive performance of the devices and systems employing such antennas by deploying beam control elements (20) to increase antenna gain at an angle less than a first angle relative to the antenna gain at angle greater than a first angle. Beam control elements are deployed in combination with the one or more antennas (12) in various systems of the present invention, such that the impact of reflected radiation from wind mill, communication, or other towers supporting the system or other nearby structures, as well as radiation from nearby wireless communication networks is decreased to an acceptable level. The beam control elements can include absorbing and reflective material and can be placed in the antenna near field to minimize costs. |
