Design of lens integrated planar antenna on chip for quasi-optical mixers

In this paper, 325 GHz antennas on chip mounted on a dielectric lens was investigated. The antennas on chip were analyzed with finite element method (FEM), including the S-parameters and impedance. The far-field radiation pattern of the lens integrated antenna is calculated synthesizing the FEM and geometrical optics (GO) based on ray launching. The extended hemispherical lens is optimized and a scaled model of the lens integrated log-periodic antenna is fabricated and measured. The measured results have good agreements with the simulation, implying the mentioned method.
