“…Numerous geometries of monopole MPAs have been investigated for UWB applications such as microstrip fed circular patch antenna utilizing a partial ground surface for UWB operations with stable radiation characteristics [10][11]. Wide Band behaviour is reported due to circular-square linked notch [12] and Saturn-shaped notch [13] on the partial ground surface with slotted circular disk monopole antenna. An electrically small size coplanar waveguide (CPW) fed circular disk monopole antenna provided very large impedance bandwidth with a flat gain [14].…”

In this paper, a microstrip fed modified circular patch monopole antenna (CPMA) with the rendered ground surface is presented for bandwidth enhancement. In order to extend the bandwidth of a demonstrated antenna, symmetrical slots and equilateral arms inverted U-slot are loaded on the partial ground and patch individually. For additional enhancement in the secured bandwidth, symmetrical notches are truncated from the bottom of the patch. The antenna has a dimension of 30x40x1.6 mm3, which is erected on low cost, FR-4 substrate with relative permittivity , permeability and loss tangent of . The proposed design is analyzed and simulated using high frequency structure simulator (HFSS). The analyzed results are validated through experimented results. The proposed antenna offers a bandwidth of 140.2 % with a maximum radiation efficiency of 94 % over the frequency scope of 2.54 GHz to 14.47 GHz. The crosspolarization levels are also found to be 20-30 dB and 12-23 dB smaller than the co-polarized level for E-plane and H-plane respectively. For better execution and assessment of proposed antenna, a parametric study has been done to analyze the performance of antenna with variations in the length of a partial ground conductor beside the other parameters. The exhibited antenna is suitable for various applications incorporating WiMAX, WLAN, UWB, C-band, X-band and UWB.
