very huge bandwidth starts from 110 GHz until 140 GHz (30 GHz). In this proposed design
antenna a minimum return loss value up to-80 dB and directivity up to 9.79 dB is achieved.
The radiated signal from the proposed design concentrated in two directions with directivity
up to 9.79 dB and 9.9 dB for 28° and 28° respectively. The design proposed cylindrical
antenna simulated using COMSOL software.
