Abstract :
We report optimal design and experiments of a novel 60 GHz imaging array using CPW-fed twin-slots on multilayered dielectric substrates. This is an all-planar structure without having to use accompanying superhemispherical substrate lenses. It has nearly symmetric radiation patterns, low surface wave losses, as well as controllable beamwidths to match the f-number of the quasi-optic system. Optimal design of the antenna/detector circuitry has been realized using FDTD analysis results of the CPW-fed slot. A 6-element array has been fabricated and tested, with results revealing excellent capabilities of this newly proposed imaging array structure.
