Abstract

This contribution presents the design and sub-mm wave measurements of a wideband dual polarized leaky lens antenna coupled to kinetic inductance detector (KIDs) to be specifically used for tightly spaced focal plane arrays. The antenna is planar and composed by two crossed slots, fed by two orthogonal coplanar waveguide (CPW) lines. In transmission, the crossed CPW lines are fed differentially in order to couple the radiation into the slots. The slot antenna feeds a dielectric lens to achieve directive patterns. The main goal of this work is to show the measurement results of the patterns and efficiency, and compare this antenna with its singly polarized version. The measured received power from an incoherent source is increased by a factor of 2 compared to a single-polarized version of the antenna.
