Dual polarization lens antenna for W-band

In this paper,we investigate a PTFE lens array operating in W band. An antenna array consisting of four pyramid hornsis used as the source of the lens. Using a lens height of 5mm and radius of 12mm the antenna has a simulated realized gain higher than 22 dBi, and sidelobe level (SLL) of −18dB. Moreover, a range of half-power beam width from 8° to 12° can be realized by simply change the distance between the lens and horns to satisfy different application.
