Abstract

This paper proposed a dual-polarized gradient refractive index (GRIN) lens antenna for ultra-wideband applications. The GRIN lens is realized by five layers of metamaterial unit cell, with a low frequency feed antenna and a high frequency feed array antenna in a shared aperture. The designed GRIN lens exhibits an impedance bandwidth of 133 % (1–5 GHz). A maximum gain of 18.6 dBi is achieved at 3.5 GHz, and the measured gain is increased by up 4.5 dB over the entire operating band when comparing with the feed antenna. The proposed antenna has great potential for applications in mobile communications, ground penetrating radar and microwave imaging.
