Abstract
This paper investigates the performance of a 3Dprinted
plastic lens operating in the 120 GHz frequency band.
An Integrated Passive Device module with built-in linearly
polarized patch antenna is used as the source of the lens. The
profile of the lens is based on elliptical shape. It is first optimized
with Geometrical Optics and Physical Optics methods. Then,
full-wave simulations are conducted to fine tune the overall
antenna-system. Using a lens height of 10 mm, the antenna has a
simulated realized gain higher than 15 dBi from 120 GHz to
130GHz. The lens and the patch antenna have just been
manufactured and measurements will be presented in the final
paper.
