Summary:This paper proposes a frequency scanning planar lens antenna operating from 9GHz to 11GHz. A four layered frequency selective surface (FSS), consisting of 9×9 cells, is designed as the lens for phase compensation. Based on Fermat's principle and transmission characteristics of the FSS, frequency scanning performances could be realized. A quasi-Yagi antenna is selected and embedded as the source at focal point to radiate well in the required band. The simulated S 11 below -10dB is from 7.7GHz to 13GHz, which covers the required band. It is demonstrated that the scan angle is from -34° to -26° with over 10dBi gain, as frequency rises from 9GHz to 10GHz. The results in simulation validate the frequency scanning performances of the planar lens antenna well.
