Abstract:
A wideband and high gain corrugated epsilon negative index metamaterial (ENG) Antipodal Vivaldi Antenna (AVA) with gain>12 dBi and working in frequency range from 10 GHz - 25 GHz (for SATCOM applications) is proposed in this paper. The overall performance of the proposed AVA is enriched by using a triangular shaped corrugation slots and pi (∏) shaped epsilon negative metamaterial cells. The ‘∏’ shaped metamaterial unit cells are positioned on the upper surface amid both radiators of AVA to emanate the intense electric field in the end-fire direction. The proposed antenna size is 22.6 mm × 15.8 mm x 1.6 mm and it is designed on the FR4 substrate. The maximum gain of the antenna is 12.2 dBi at 14.5 GHz.
