Development of planar dielectric passive microwave circuits and antennas

摘要

In this paper we propose an approach for designing compact all-dielectric passive microwave/mm-wave components. Our design is based on an extremely thin layer of high-permittivity dielectric which creates a large permittivity contrast with its adjacent dielectric/substrate and can be built using two-dimensional printing fabrications. Couplers, transmission lines, and various antennas such as multimode, multisegment, and wideband antennas are investigated, fabricated, and discussed.
