Wideband Wide-Angle Scanning Tightly Coupled Dipole Array with FSS Superstrate

摘要

A novel Tightly Coupled Dipole Array (TCDA), operational in Ku-band and with integrated balun is presented. In this paper, the traditional dielectric superstrate is replaced by frequency selective surface (FSS) for wideband and wide-angle impedance matching. The proposed TCDA has low-profile architecture. A prototype is simulated and the results show that the scanning angle ranges up to 85° in E-plane (with VSWR<3) while 80° in H-plane (with VSWR<3.2).
