Novel planar AMC for low profile antenna applications
conference contribution
posted on 2012-06-26, 13:30 authored by M.K.T. Al-Nuaimi, William WhittowWilliam WhittowIn recent years, the realization of Artificial Magnetic
Conductors (AMCs), also designed as high impedance surfaces
(HISs) or Perfect Magnetic Conductors (PMCs), has been an
active area of research as they can replace perfect electric
conductors (PECs) for low profile antennas and other microwave
applications. In this paper a planar AMC using circular split
ring resonators (SRRs) printed on grounded dielectric substrate
is proposed. The simulation results verify that the magnetic
conductor is successfully accomplished over narrow bandwidth ≈
0.25 GHz. As an antenna application, the return loss of a
horizontally positioned dipole antenna placed above the
proposed AMC and the conventional PEC ground planes are
investigated. The results confirm that the split ring resonators
can successfully be used to replace the antenna conventional
ground plane in order to improve the strength of the radiating
fields and to reduce the global thickness of the low profile
antennas. The performances of the proposed AMC are studied
using finite element method ANSOFT−High Frequency
Structure Simulator (HFSSTM v.10) and numerical simulation
model is developed to predict the reflection phase profile of such
structures.
