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...
We report on two silicon based antennas for future large-format THz focal plane imaging arrays. The silicon-based corrugated horn antenna shows return loss below 15 dB and antenna gain over 20 dB in the 320–360 GHz frequency band. The 1.9 THz silicon microlens antenna has been designed and microfabricated. The simulated 1.9 THz antenna shows good 2-D beam radiation pattern and aperture efficiencies...
This contribution presents the first demonstration of a linear polarized ultra wide bandwidth antenna, the Leaky Lens Antenna, coupled to a Kinetic Inductance Detector (KID). The two of them function as an ultra sensitive receiver over a bandwidth ranging from 0.15 GHz to 1.5 THz. The system has been manufactured and characterized in terms of power efficiency, and radiation pattern properties. The...
A silicon lens antenna suited for future integrated terahertz arrays has been proposed recently. The antenna consists of an extended hemispherical silicon lens fed by a leaky-wave waveguide feed. The primary advantage is that the antenna is compatible with silicon micro-fabrication techniques as only a small sector of the lens is actually used. Moreover, it can be easily integrated with other silicon...
We present a novel antenna concept suitable for future integrated arrays at terahertz frequencies. The antenna consists of an extended hemispherical lens antenna fed by a leaky wave waveguide feed. In this contribution we present the antenna lens analysis and design.
