Abstract
A Ultra Wideband circular patch antenna has been designed for the Ka band applications with an operating frequency range of 29.4GHz to 39.3GHz covering 10GHz of bandwidth. The patch has been shorted with the ground by using a shorting pin which led to the generation of Ultra wideband width. Flame Retardant Glass epoxy is taken as substrate material which is having a thickness of 0.21mm and a 50Ω coaxial cable has been used to excite the antenna. Shorting pin technique has been implemented to attain the Ultra wideband width of operation. The overall dimension of the antenna is 8.4mm×8.4mm×0.21mm. The Proposed antenna is having Ultra wide bandwidth covering the ka band frequency range from 29.4GHz to 39.3GHz covering 10GHz of bandwidth with a return loss value less than -10dB for entire bandwidth. Commercially available 3D simulator Ansys HFSS software has been used to design the proposedantenna.
