Abstract
A micro-lens antenna concept suitable for future tightly spaced terahertz heterodyne arrays has been proposed recently. The antenna consists of a waveguide feed which uses a leaky wave cavity to enhance the directivity and illuminate an extended hemispherical shallow lens efficiently. Two orthogonal double-slot apertures (irises) are designed to realize the dual-polarization operation. In this paper, we design and simulate the dual-polarized micro-lens antenna with an aperture diameter of 2.5mm and the maximum directivity of 21 dB at 300GHz.
