- 論文の詳細を見る
This paper describes a multibeam antenna which uses switched parasitic and switched active elements to obtain multiple simultaneous directional beams that can be steered in azimuth. A 13 element monopole multibeam array has been optimised for gain and front to back ratio. Results from numerical simulation and measurements in an anechoic chamber are presented. The 13 element array can achieve up to three beams simultaneously with a minimum gain over 360° azimuthal coverage of 1.2 dB less than the maximum gain. Located on a ground plane with diameter of 2λ at 1.5 GHz, the maximum elevation angle was 20.2° with -3 dB vertical beamwidth of 88°.
