摘要：
This paper presents the design and simulation procedure of a 1-bit 256 -element linearly-polarized (LP) reconfigurable transmitarray antenna (RTA) in Ka-band. The RTA unit-cell (UC) size is 0.48 lambda x0.48 lambda x0.11 lambda, where a pair of p-i-n diodes are integrated to realize an 180 degrees phase shift and thus a 1-bit discrete phase quantization is made. 3-D beam scanning is then realized by certain discrete phase distribution calculated by ray tracing method (RTM). According to full wave simulation results, the peak gain is 21.3dBi/21.5dBi in E/H-plane at 28GHz, respectively. Moreover, it has good beam scanning performance with scanning range of 45 degrees in both E-plane and H-plane.
