The U-slot patch antenna, a single-layer single-patch
antenna on a relatively thick substrate ( 0 08 0), is a wide-band
antenna with an impedance bandwidth in a range of 20%–30%,
which is about an order of magnitude larger than that of the regular
patch antenna. Recently, it was shown that a half U-slot patch
antenna, with half of one of the dimensions of the U-slot patch,
maintains similar wide-band behavior. The half-structure was
also successfully applied to the U-slot with shorting wall. In this
paper, new results on half structures, not previously published, are
presented. First, the shorting pin technique is used to reduce the
size of the half U-slot patch antenna. By both simulation and experimental
studies, it is concluded that the impedance bandwidths,
radiation patterns, radiation efficiencies and gains of the halfstructures
are comparable to the corresponding full structures.
Bandwidth of 28.6% and radiation efficiencies exceeding 90% are
obtained for the half U-slot patch with shorting pin. Radiation
patterns are stable across the matching band. Second, it is shown
that a structure obtained from halving the E-shaped patch, which
is a derivative of the U-slot patch, also maintains its wide-band
behavior.
