antennas to have a low profile configuration. In such a design,
the overall height of the antenna structure is usually less than
one tenth of the operating wavelength. A fundamental challenge
in low profile wire antenna design is the coupling effect of a
nearby ground plane. A compact highly directional dipole
antenna backed by our novel proposed planar artificial magnetic
conductor (AMC) structure with an overall height of 0.034 λ is
investigated. Two different dipoles are used in this study, wire
and printed dipole antenna over the proposed AMC. A
comparative study is conducted to study the return loss of the
dipole antenna parallel above the proposed AMC and the ideal
perfect electric conductor (PEC). A numerical simulation model
using Ansoft high frequency structure simulator (Ansoft-
HFSSTM) is developed to predict the reflection phase stop band of
the proposed structure. The peak gain of the antenna over the
proposed AMC is close to 8 dBi.
