| 摘 要： | 为了克服微带天线的横向尺寸需要满足半个波长的限制,本文提出了一种基于复合左右手传输线技术的二元阵天线.该天线阵由结构相同的两个天线阵单元构成:天线阵单元由3个辐射片、辐射片之间的交指电容和导通辐射片和接地板的短路针组成.辐射片、短路针、天线阵的基片和接地板构成了复合左右手传输线结构.天线阵单元之间通过弓形连接线连接,通过调节弓形连接线两个端口到馈源之间的距离来调节天线阵单元之间的初始相位差.在关心频段内,数值计算得到的二元阵天线的S参数与实际测量结果符合得很好,并且零阶谐振频率与用等效电路理

| Abstract: | To overcome the limitation that the linear transverse dimension of microstrip antenna is of the order of half wavelength,a two-element antenna array has been proposed with composite right /left-handed transmission line metamaterials in this paper.The antenna array is made of two same antenna elements.Each element consists of three radiating patches,interdigital capacitance between two radiation patches and shorted pin connecting radiating patch with ground plane.Therefore,a composite right /left-handed tran... |
