摘要

提出了一种新型的紧凑型左/右复合基板集成波导漏波天线。利用蘑菇启发的单元电池来实现CRLH传输性能和能量泄漏。周期性加载的金属通孔，作为一个内部1:1的功率分配器，沿着SIW结构的中心线，导致一个紧凑的天线尺寸。LWA可以看作是一个天线阵列，它的两个单元分别被两个新产生的准te10模式激发，从而提高了天线的峰值增益。仿真结果与实测结果吻合较好。连续波束扫描特性表明，所提出的设计是一种工作在ku波段的平衡频率扫描工作。

Compact CRLH-SIW Based LWA Array With Periodical Loading for Ku-Band Applications

|A novel compact composite right/left-handed (CRLH) substrate integrated waveguide (SIW) based leaky wave antenna (LWA) is proposed. Mushroom-inspired unit cell is utilized to achieve CRLH transmission property as well as energy leakage. Periodically loaded metallic vias, which act as an internal 1 : 2 power divider, are along the center line of the SIW structure, leading to a compact antenna size. The LWA can be regarded as an antenna array whose two elements are excited by two newly produced quasi-TE 10 modes, respectively, and therefore, the antenna peak gain is enhanced. Good agreements are obtained between the simulated and measured results. Continuous beam scanning feature indicates that the proposed design is a balanced frequency scanning work operating in Ku-band.
