An enhanced hexagonal shaped planar antenna is presented for ultra-wideband (UWB) applications. In this paper,
a hexagonal patch with six circular cuts at its vertices is designed on FR4-substrate with 50 Ω microstrip
triangular tapered feed line and a bevelled partial ground plane with five half circular sleeves. The design is
investigated using the high-frequency structure simulator (HFSS). The simulated and measured scattering
parameter S11 (Reflection Coefficient) results show good impedance matching in the frequency range (3- 27.57
GHz) satisfying return loss (RL = |S11|) ≥ 10 dB with a percentage bandwidth (PBW) of 160.75%. High gain and
efficiency, radiation pattern similar to the electric dipole in E-plane and good omnidirectionality in the H-plane
are achieved.
