III. DESIGN OF DUAL FEED APERTURE
COUPLED ANTENNA WITH E
SHAPED PATCH
The Dimensions of E shaped patch antenna is shown in
table 2 [5][9]. It consists of a E shaped patch by cuting slots
onto the patch with equal length. It gives the impedance
bandwidth 14.8% (9.78-11.34 GHz) and return loss -31.57
dB (at 10.68 GHz). The reture loss and VSWR are shown in
figures 3.2 and 3.3 and the radiation pattern is shown in
figure 3.4.
