Design and Analysis of a Double Slotted with Multiple Strips Vivaldi Antenna for High-Speed 5G Communications

This research work focuses on the design, analysis and simulation of a multiband Vivaldi antenna at unlicensed millimetre wave ISM band with resonance frequency-band of 55–66 GHz for high capacity 5G communication framework. The simulation of the proposed antenna is carried out using Rogers RT 5880 substrate. The modified noble design of the double-slotted Vivaldi antenna (DSVA) is proposed with few corrugations and grating elements in order to ameliorate the gain and directivity as well as −10 dB impedance bandwidth. The dimension of the proposed antenna is 70×40×1.07 mm³. This design is primarily focused in attaining a miniaturized antenna having good antenna characteristics with minimum weight and cost and simplicity of integration utilizing feed-networks. The proposed Vivaldi antenna provides excellent VSWR of less than 2 and the gain near about 13–15 dB of six obtained resonance frequencies in frequency-band 55–66 GHz which is very much suitable for high-speed 5G communication. The gain of this antenna is far better than some other recent conventional Vivaldi Antennas.
