Abstract :
A dipole antenna with a double electromagnetic band gap (EBG) reflector is presented for wide operating bandwidth and high gain. The antenna is excited by a printed dipole centrally positioned above the planar double-layered EBG structures which is partially loaded with a ground plane. The simulated and measured results show that a wide impedance bandwidth of 44.4% (SWR<;2) over the frequency range from 2.8GHz to 4.4GHz is achieved. Stable radiation patterns with low cross-polarization levels and an achieved gain of ~8.5 dBi over the ground plane of 1.167λ, ×1.167 λ, is found across the entire operating bandwidth.
