DESHIMA (Deep Spectroscopic High-redshift Mapper) is an instrument aiming at efficiently making spectroscopic redshift measurements of sub-mm wave galaxies (SMGs), thereby providing about the formation and the evolution of stars and galaxies. The aim of this work is to provide a preliminary study into the design of a wideband leaky lens antenna coupled quasi-optical system within a 1:3 bandwidth....
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...
This contribution presents the design of a dual polarized leaky lens antenna coupled to a Kinetic Inductance Detector (KID) in order to enable a broadband THz detector for future space applications. The designed antenna presents high aperture efficiency and clean symmetric patterns.
We propose an array of connected leaky-wave slots as feed of an extended hemispherical dielectric lens, for broadband imaging applications. Simulations of the entire structure, including array and lens, are performed by combining a spectral Green's function approach and an accelerated physical optics method. The antenna characteristics are investigated over a 4∶1 bandwidth parametrically varying the...
