In this paper, A lens antenna with high gain is proposed. The antenna is composed of the microstrip antenna and the hemisphere dielectric lens, and the lens is loaded on the top. The polyethylene is used to fabricated the hemisphere dielectric lens. The antenna has dimensions of 47.58 mm × 47.58 mm × 24.79 mm, which is corresponding to the electrical size of 1.586λ0×1.586λ0×0.826λ0, where λ0 is the free-space wavelength at 10GHz. The impedance bandwidth (return loss<-10dB) is 12.7%(9.24 GHz-10.51 GHz), and the peak gain is 9.06 dBi. The hemisphere dielectric lens can improve the gain of the microstrip antenna. The proposed lens antenna is suitable for wireless communications systems.
