Highly integrated transmitting and receiving phased array with multi-channels and high efficiency in K/Ka-band SatCom application
Zhang, Qiaoshan; Shi, Xiaowei; Gao, Steven; Li, Yan; Luo, Qi; Wan, Jixiang; Xue, Zhaoxuan; Wen, Lehu (2021-07-26)A highly integrated K/Ka-band phased array with duplexing channels for transmitting and dual circularly polarized channels for receiving is presented. To increase both the efficiency and channel isolation, a novel architecture ... -
A Low-Profile Beam-Steering Reflectarray with Integrated Leaky-Wave Feed and 2-Bit Phase Resolution for Ka-band SatCom
Zhang, Qiaoshan; Zhang, Mingtao; Shi, Xiaowei; Gao, Steven; Luo, Qi; Chen, Lei; Wan, Jixiang; Wang, Xudong (2021-09-15)A novel reflect array (RA) with ultra-low-profile and 2-bit phase quantization beam-steering ability is presented in this paper. To reduce the profile, a Leaky-wave feed is used to excite the RA with enhanced illumination ...
