| 摘 要： | 利用等效磁流法详细地分析了含有六个弯头的一般曲折微带线单元的辐射场,由此推导出获得各种极化波的单元尺寸设计条件。在设计面阵时,对单元间和线阵间的耦合作了实验性的研究,以单元间、线阵间的阻抗影响最小作为去除耦合的标准。对加工出来的右旋圆极化平面阵列的测试结果表明,500MHz 通带上的驻波特性较好,方向特性、增益也与理论值较为吻合。

| Abstract: | In this paper,the radiation field of the general bent micro-strip line element including six right angle bends has been analysed indetail by using the method of equivalent magnetic current.It has beendeduced from this that the designed conditions of element size whichradiate all kinds of polarized wave.The couples between elements andthose between linear arrays have been studied in experiment while theplane array is desinged.The minimum affects of input impedance has beenset for the standard of elimination of couples between elements andbetween linear arrays.The test results of right circular polarized planearrays show that the characteristics of standing wave in 500MHz passed-band are well,the characteristics of directivity and gain coincide withthe theoretical values very well.Finally,some designing formulae andcomputer programs are presented in appendix. |
