Beamforing Network Design of Phased Array Antennas for Marine Radar Application
碩士 === 國立臺灣科技大學 === 電子工程系 === 105 === This thesis presents a 9.4-GHz Butler matrix for the marine radar application. The matrix consists of 3 dB couplers, crossovers and fixed phase shifters. The 8×8 and 8×16 Butler matrices are realized by suspended striplines and microstrip lines, respectively. Tw...

The 8×8 Butler matrix realized by the suspended striplines with 1×8 slot antennas has successfully yielded 8 main beams pointing to -25˚(4L)、-18˚(3L)、-11˚(2L)、-4˚(1L)、4˚(1R)、11˚(2R)、18˚(3R)、26˚(4R), respectively.

As compared to the theoretical switched angles, the average angle error is 1.1˚. Chao-Hsiung Tseng 曾昭雄 2017 學位論文 ; thesis 68 zh-TW |
