    Abstract

    We propose a radiometer receiver array based on a silicon microlens array and MMIC detectors at 200 - 250 GHz. The paper describes the array concept and details microlens development. Planar Gradient Refractive Index (GRIN) lenses have been chosen for the array. Fabrication process based on DRIE etching of silicon has been developed, and lenses designed. The first measurement results of the lens are presented.
