Abstract :
In this paper a dielectric bifocal lens for a 60 GHz wide angle scanning antenna is presented. The lens is designed with the construction algorithm of Holt & Mayer. The construction algorithm is improved in a way that the bend of the lens towards the focal plane is no longer determined by trial and error but calculated numerically with a bisection method. Finally a zoned bifocal lens made of high density polyethylene (HDPE) is simulated and compared to a conventional plano-convex one of the same diameter.
