A Cryogenic 180° Planar Hybrid for High-Sensitivity Radio Astronomy Receivers

open access: yesIEEE Access
A 180° hybrid is a fundamental component in microwave circuits, functioning as both a signal splitter and combiner in radio astronomy and space system applications. An ideal 180° hybrid provides equal power division with a 180° phase

Compact Circularly Polarized Patch Antenna Using a Composite Right/Left-Handed Transmission Line Unit-Cell [PDF]

open access: yes, 2013
A compact circularly polarized (CP) patch antenna using a composite right/left-handed (CRLH) transmission line (TL) unit-cell is proposed. The CRLH TL unit-cell includes a complementary split ring resonator (CSRR) for shunt inductance and a gap loaded ...

Fabrication and characterization of high current-density, submicron, NbN/MgO/NbN tunnel junctions [PDF]

open access: yes
At near-millimeter wavelengths, heterodyne receivers based on SIS tunnel junctions are the most sensitive available. However, in order to scale these results to submillimeter wavelengths, certain device properties should be scaled.

Microwave characterization of slotline on high resistivity silicon for antenna feed network [PDF]

open access: yes
Conventional silicon wafers have low resistivity and consequently unacceptably high value of dielectric attenuation constant. Microwave circuits for phased array antenna systems fabricated on these wafers therefore have low efficiency.
