Firstly, T-slots are inserted diagonally at the corners of parabolic ground plane in order to increase the directivity. Thereafter, for the further improvement in the directivity as well as gain the ellipse slot in circular patch has also been introduced. The microstrip feed line is given for the proposed unidirectional antenna. The simulation analysis of the antenna is done on software CST Microwave Studio using FR-4 substrate with dielectric constant 4.3. The simulated results and parametric analysis show a good return loss with respect to -10 dB. The radiation pattern characteristic, gain characteristic, VSWR pattern and surface current distribution performance of the antenna have also been compared at different resonate frequencies.
