【摘要】 本文提出一种新式背射天线,它把单线背射螺旋作为短背射天线的馈源。这种天线具有结构简单、馈电方便、频带宽、增益中等、易于产生圆极化波等特点,较相同直径接地板的螺旋天线有更优的性能。更多还原

【Abstract】 A new backfire antenna is developed. The reflector of a short backfire antenna has a new feed -- monofilar backfire helix. The advantages of this new antenna are simple structure, easy to feed, medium gain and circularly polarized radiation. The characters of the antenna are better than a helix of same ground plane.更多还原
