In this article, an octagonal patch antenna with U-shaped slot for UWB application is proposed. The antenna consists of a three-layered section such as patch, Substrate and Ground. Here, Patch and Ground are the perfectly conducting foil mounted on a Flame Retardant 4 (FR -4) dielectric material whose permittivity Ɛr = 4.4 and loss tangent δ = 0.002. The radiating element and ground are fed through a microstrip line using a Lumped Port. A U- shaped slot is etched on the center of patch to disseminate the surface current throughout the patch whose sectional area is 15 x 15 mm2. Also, a Defective ground Structure is introduced in the ground plane which is provides broadened bandwidth, enriched gain, improvises the radiation characteristics of the antenna with mutual coupling between the proximate sectional areas. The complete measurement of the proposed antenna is 28 x 28 x 1.6 mm3. The antenna is design and analyzed using High Frequency Simulator software (HFSS) platform. The simulated outputs of the antenna such as Reflection Co-efficient, Voltage Standing Wave Ratio (VSWR), Fractional Bandwidth (FBW), Peak Gain, Radiating Efficiency and Impedance Matching are obtained and compare with the existing designs. Thus, the proposed antenna resonates with the bandwidth of 3.7 GHz to 13.5 GHz whose Fractional Bandwidth (FBW) is 114% with a peak gain of 5.6 dBi are obtained, which denotes that the antenna is capable of radiating for UWB applications.

The radiating element and ground are fed through a microstrip line using a Lumped Port. A U- shaped slot is etched on the center of patch to disseminate the surface current throughout the patch whose sectional area is 15 x 15 mm2. Also, a Defective ground Structure is introduced in the ground plane which is provides broadened bandwidth, enriched gain, improvises the radiation characteristics of the antenna with mutual coupling between the proximate sectional areas. The complete measurement of the proposed antenna is 28 x 28 x 1.6 mm3. The antenna is design and analyzed using High Frequency Simulator software (HFSS) platform.
