摘要

本文提出了一种具有方向图可重构天线的对称加权薄阵列，以实现广角扫描性能。通过正确选择各单元的加权函数、激励和状态，阵列可以在宽角度扫描时，使其主波束相对于宽频面-77°~ +77°，旁瓣电平(SLL)几乎比最大值低-10dB。在h平面上，3dB波束宽度覆盖范围几乎在-98°到+97°之间。

A novel symmetric weighted thinned array with pattern reconfigurable antenna to achieve wide-angle scanning with low side lobe level

In this paper, a novel symmetric weighted thinned array with pattern reconfigurable antenna is proposed to achieve wide-angle scanning performance. By properly selecting the weighted function, excitation and states of each element, the array can scan its main beam form -77° to +77° with respect to broadside with side lobe level (SLL) almost -10dB below the maximum when scanning to the wide angle. And the 3dB beam width coverage is almost from -98° to +97° in H-plane.
