1 Half U-slot Patch Antenna with Shorting Wall Antenna Geometry
Figure 1 shows the geometries of the two shorted half-U-slot patch antennas under study. Figure 1a is the half U-slot patch with shorting wall. It has the dimensions of length and width . The patch is supported by the shorting wall and probe feed wire in the air 10mm above the ground plane. As shown in Figure 1a, one side of the patch is shorted to the ground. The coaxial feed is excited 12mm away from the open edge and it is touching to the other edge of the patch.
