Abstract
In this paper, a low-profile and unidirectional spiral antenna is proposed. The antenna is backed by a Meta-material (MTM) absorber realized with circular patches on a magnetic substrate. The impact of the meta-material absorber on the antenna characteristics such as reflection coefficient, polarization and gain has been investigated. Good performances are obtained in a low-profile configuration using HFSS EM software simulation.
