Abstract: This paper presents the implementation of a near-field focusing (NFF) antenna on basis of radial line slot array (RLSA). The proposed NFF-RLSA antenna is derived from the conventional single ...

Abstract: A millimeter-wave (mmW) dual-band dual-circularly polarized high-efficiency radial line slot array (RLSA) antenna fed by gap waveguide technology is presented in this paper. By introducing ...
