    The characteristics of a small antenna using an H-shaped
    microstrip patch are studied. Significant reduction of antenna size can
    be realized when the H-shaped patch is used instead of the conventional
    rectangular microstrip patch antenna. The theoretical analysis is
    carried out based on the finite-difference time-domain (FDTD) method.
    The FDTD programs are developed and validated by available measurement
    results. The effects of various antenna parameters on the resonant
    frequency and radiation patterns are shown. Several design curves are
    presented and the electric current distributions on the patch and ground
    plane are described. This antenna is suitable for applications where
    small size and broad beamwidth are required
