A Low-Profile Pentagon Inscribed in Circle Shaped Wide Band Antenna Design for C-Band Applications

A low profile pentagon inscribed in a circle-shaped wideband antenna is designed for c band applications and broadband applications as well is proposed in this letter. The proposed antenna consists of a micro-strip patch in the pentagon inscribed in a circle with the microstrip line feed and a rectangular ground plane with DGS. The antenna has 9×19.8mm
²
size, thickness of 1.6 mm, 4.4 dielectric constant, and 0.02 tangent loss. According to the simulation results, the proposed antenna bandwidth has operating in the frequency band of 4.93GHz to 9.01 GHz and resonant at a frequency of 7.6GHz. The final proposed antenna was simulated with FR4 substrate. The design of antenna is analyzed, simulated, and optimized using ANSYS HFSS.
