Abstract:
The ways of converting a wide band, electrically
small in size, bi-directional quasi magnetic antenna into a unidirectional one are investigated. The purpose is to develop a
magnetic wall parallel to the antenna which provides low-profile
unidirectional designs, without sacrificing the bandwidth too
much. Initial attempts to preserve the wide bandwidth caused
some problems like pattern splitting at the broadside of the
antenna and this problem has been solved by introducing an
aperiodic AMC. An operational bandwidth for a VSWR = 2 of
44% in the X-band is achieved. The total height of AMC and
the antenna is ?/6.2 at fmin and ?/4 at fmax.
