Enhanced ultra-wide band hexagonal patch antenna

الملخص EN

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.
