摘要
多波束天线作为一种常用的阵列天线,能够调和毫米波天线频率与增益、覆盖之间的矛盾,以达到高增益、广覆盖的特点。文章提出了基于六端口Buter矩阵的双极化多波束天线阵列,达到了宽角度低旁瓣扫描的效果,阵列在垂直方向形成四角度波束,分别为-12°、+40°、-40°和+14°,在波束扫描范围内,旁瓣电平优于-14dB,最大增益为18dBi。
As a common antenna array,multi-beam antenna gained wide usage in alleviating the contradiction between gain,coverage and frequency,and contributes to high gain and wide propagation.A dual-polarized multi-beam antenna array based on Butler matrix is proposed in this paper,with a characteristic of low sidelobe level in wide angle scanning,within range of the beamscan,the antenna proposed gains sidelobe level below-14dB and the maximum gain of 18dBi.
