Abstract: In this letter, a high-order mode (TE340-mode) empty substrate-integrated cavity (ESIC) fed high-gain circularly polarized 2 × 2 patch antenna array is presented. By using the ESIC ...
Abstract: Multibeam systems are a key technology for the high-speed links of the next-generation communication standards. Due to the stringent space constraints for allocating antennas on a platform, ...
