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 Antipodal Vivaldi Antenna (AVA) is enriched by using a triangular shaped corrugation slots and pi (Π) shaped epsilon negative metamaterial cells. The ‘Π’ 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 proposed antenna is then fabricated using photolithography process and tested for its performances. There is good agreement between simulated and measured results. The measured gain varies from 6.2 – 10.7 dBi
