We also design here, unequal slots onto the patch
antenna [5]. The structure of circularly polarized E patch
antenna is shown in figure 3.5.
The results of circularly polarized antenna with unequal
slots onto the patch are shown in figure 3.6 and figure 3.7.
The impedance bandwidth is 15.3% (9.59-11.19 GHz) and
return loss was -34.13 dB (at 10.53 GHz) [7]. This structure
gives batter impedance bandwidth.
