五波束拋物環(huán)面天線
FIVE-BEAM PARABOLIC TORUS REFLECTOR ANTENNA
-
摘要: 本文首先給出了拋物環(huán)面天線的輻射場(chǎng)公式,然后利用給出的公式設(shè)計(jì)和研制出一個(gè)90角域的五波束拋物環(huán)面天線,并示出了該天線五個(gè)波束的測(cè)試方向圖和中心波束的計(jì)算方向圖,計(jì)算值和測(cè)量值吻合很好。最后,還介紹了中心波束和邊緣波束的增益測(cè)量值。

Abstract: The radiation field formulas are given for a parabolic torus reflector antenna. A five-beam parabolic torus antenna with 90?azimuth coverage has been designed and developed. An experimental radiation pattern of these five beams and theoretical patterns of the central beam of the antenna are also given. Comparison between calculated and measured patterns shows they are in good agreement. Finally, the measured gain data for the central beam and the edge beam are presented. -
