In this paper, the antenna is mainly composed of a
radiation patch with good radiation performance .The
proposed antenna possesses a method to minimize the
monopole antenna by loading of inverted L-strip over the
conventional radiator patch antenna to lower the height of
the antenna. The ground was vertically extended toward
two sides of the single radiator. Therefore, the large space
around the radiator that is usually wasted can be
effectively saved. The proposed structure is illustrated in
Fig. 1.
