Summary:
This letter presents a circularly polarized square slot antenna used for navigation system. A tuning stub protruded into the slot from the narrowed stripe at the end of the signal strip of the CPW is used to obtain good impedance matching. A measurement showed that the bandwidth below -10dB of the antenna varied from 1.15GHz to 1.71GHz , and the Axial Ratio below 3dB is from 1.14 GHz to 1.75GHz. The radiation pattern is bi-directional.
