Application of Patch-Removal to Spiral Antenna Backed by Mushroom-Shaped EBG Reflector

摘要：

This paper presents a spiral antenna backed by a mushroom-shaped EBG reflector.The antenna characteristics are investigated on the basis of the electric and magnetic fields obtained by using the finite-difference time-domain method.The investigation reveals that removing some patches from the EBG reflector improves the axial ratio.
