✦ Synopsis

The variations of the dimensions and locations of two stacked parasitic elements on the input impedance SWR bandwidth and radiation patterns of aperture-coupled rectangular microstrip antennas are analyzed. It is found that the SWR bandwidth can be improved by selecting appropriate sizes and locations of the parasitic patches. A 45% bandwidth of patch antennas was attained for SWR F 2.2. Experimental results are obtained to verify the theory.

Figure 8 Measured gain at 1.55 GHz for both antennas described in Figures 1 and3 The radiation patterns measured for both antennas with a rotating dipole at the central frequency of 1.5.5 GHz is shown in Figure 7. They present an axial ratio of 1.5 dB in the half-power beamwidth and are still better
