Abstract:

This paper reports the design of a miniaturized 1 X 4 Antipodal Vivaldi Antenna (AVA) for 5th generation (5G) communication applications. The size of proposed AVA is 28.8 mm X 24 mm x 0.254 mm and it is designed by using Rogers RT5880 substrate. Initially, 1 x 4 AVA array (AVA-A) is designed with slots in between two antenna elements. This designed AVA-A operates over three frequency bands which are 24.91 GHz to 33.18 GHz, 34.95 GHz to 36.58 GHz, and 38.34 GHz to 39.38 GHz and provides gain in the range of 8.47 dB to 12.63 dB. The performance parameters of AVA-A is enhanced by incorporating corrugations in it. The AVA-A with corrugations(AVA-AC) enhances gain, bandwidth and front to back ratio of an antenna. The proposed AVA-AC provides enhanced and nearly constant gain of 8.2 dB to 13.2 dB over 24.04 GHz to 40.85 GHz frequency range which includes three bands of 5G communication spectrum (24.25 GHz to 27.5 GHz, 31.8 GHz to 33.4 GHz, and 37 GHz to 40.5 GHz). Also, results shows that, AVA-AC provides stable radiation pattern over its complete operating range which makes AVA-AC suitable for integration in 5G communication devices.
