Paper Abstract
In this communication design and performance of a modified semi elliptical microstrip patch antenna is proposed to achieve circularly polarized broadband performance. The proposed structure consists of a semi-elliptical patch having a D-shaped slot designed on three layered substrate material. The structure has two FR-4 substrates separated by a foam material having 1 mm thickness. The simulation analysis is carried out by using IE3D simulation software. The proposed antenna covers entire median band (3.4 to 3.69 GHz) allocated for Wi-Max communication systems. Two modes having resonance frequencies very close to each other (3.36 GHz and 3.66 GHz) are excited to achieve broadband performance. The impedance bandwidth of proposed antenna is close to 21%. The minimum axial ratio is close to 1.8dB while axial ratio bandwidth is close to 4.63%. The radiation patterns within bandwidth are almost identical in shape.
