Abstract
A compact dual frequency triangular ring patch antenna has been designed for the radiolocation and fixed satellite applications in the X and Ku bands with an operating frequency of 8.55GHz and 19.44GHz. The patch has been considered as triangular ring to get the necessary frequency of operation. Flame Retardant Glass epoxy is taken as substrate material which are having a thickness of 2mm and a 50Ω microstrip line has been used to excite the antenna. Slotted patch technique has been implemented to attain the dual frequency of operation. Proposed antenna work as two radiators of which one is outer perimeter of patch and the other is the inner perimeter. The overall dimension of the antenna is 14.3mm×14.3mm×2mm which is 0.61λ×0.61λ making the proposed antenna a compact one. The Proposed antenna is having dual frequency of operation at the frequencies of 8.55GHz and 19.44GHz with again of 6.06dB and 5.82dB respectively. Commercially available 3D simulator Ansys HFSS software has been used to design the proposed antenna.
