The Design of A 3-18GHz Tightly Coupled Dipole Array with An FSS Superstrate

摘要：

　　This paper presents a design for ultra-wideband tightly coupled dipole array(TCDA)with a Marchand balun and a printed frequency selective surface(FSS)for wide angle scanning.The simulation results show that the infinite array achieves 6:1 bandwidth(3-18GHz)with VSWR<2.5 in the broadside while scanning up to ±45° in the E and H planes for VSWR<3,<-20dB cross-polarization.The FSS superstrate replaces the bulky dielectric layer,leading to a low profile and low weight structure.In comparison to strip feed line,the tapered micro-strip feed line makes the model easier to fabricate at high frequency.
