Abstract :
This paper presents a technique for restoring the inherent axial ratio without a reduction in the radiation efficiency. For this purpose, an EBG reflector [2][3] is adopted and modified. The EA-spiral with the EBG reflector is analyzed using the finite-difference time-domain method and the radiation characteristics are revealed.
