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

IEEE 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

Integration of parallel-plate ferroelectric varactors with BCB-on-silicon microstrip circuits

, 2004
A four mask process is developed to integrate parallel-plate ferroelectric varactors with BCB film microstrip circuits. A tri-layer stack, consisting of bottom electrode (M1), ferroelectric film and top electrode (M2), deposited on silicon substrate is ...

Feeding‐line‐based decoupling patch antennas

IET Microwaves, Antennas & Propagation
Mutual coupling among multiple antennas has been a problem needed to be tackled in multiple‐input‐multiple‐output (MIMO) systems. A decoupling method based on short decoupling feeding lines (DFLs) for MIMO patch antennas is proposed.

MODELING OF SHIELDED MICROSTRIP TRANSMISSION LINES [PDF]

, 1996
Microstrip lines are widely used not only in microwave circuits, but also in very large scale integration (VLSI) and high frequency circuit boards. Initially microstrip lines were analyzed mainly in the frequency domain, but now time domain analysis is ...
