Improving L-band Printed Monopole Antenna Performance Using High Impedance Surfaces

Just few years ago, a new branch in microwave engineering developed with the emergence of Metamaterials (MTMs). The implementation of the first artificial medium with negative effective dielectric permittivity and magnetic permeability opened the door to the experimental study of a new kind of media: left-handed media (LHM). In this paper, the study and design of a printed monopole antenna operating in L band based on High Impedance Surface (HIS) substrate is proposed. The aim is to simultaneously reduce the antenna size and maintain the operating frequency but also to satisfy the desired antenna performance. The EM simulations results of directivity, gain and reflection coefficient are of great importance and affirm the employing of metamaterials in such applications.
