Abstract :
A dual-band slot antenna with an asymmetrical tuning stub added two pairs of symmetrical slot patches inside the slot is proposed for reducing the peak cross-polarization level. The asymmetrical tuning stub can be used to tune the input impedance matching for the bandwidth improvement but possess very high cross-polarization levels. The two pairs of symmetrical slot patches are used to reduce the peak cross-polarization level, and the suppression is about 9 dB lower than that of the design without slot patches. Details of the design are presented, and simulated and measured results are also presented and discussed.
