Microstrip antenna with integrated phase shifter [PDF]

, 1999
International audienceA microwave microstrip probe‐fed antenna with an integrated voltage‐controlled phase shifter is investigated. The phase shifter used is a microstrip 90° hybrid loaded by two varactor diodes, allowing a 40° phase shift.

Influences of Ambient Temperature on Dual-Temperature-Zone Pulse Tube Refrigerator with Acoustic Power Recovery Phase Shifter

Zhileng xuebao
Pulse tube refrigerators are widely used in space detection and quantum computing due to their low vibration output at the cold end and high reliability. Dual-temperature-zone pulse tube refrigerators can simultaneously achieve dual cooling temperatures.

High power phase shifter [PDF]

, 2005
One of the approaches to power distribution system of a superconducting proton linac under discussion at FNAL requires development of a fast-action, megawatt-range phase shifter. Using a couple of this kind of devices with a waveguide hybrid junction can

A 7-Bit Vector-Sum Phase Shifter for LEO Satellite Communication in 90-Nm CMOS Process

IEEE Access
This paper presents a 7-bit vector-sum phase shifter for low-earth-orbit satellite communication. The phase shifter consists of a differential-type quadrature all-pass filter (QAF) and an analog differential vector adder, where a matching network is ...

Circularly Polarized Microstrip Ferrite Phase-shifter with Uneven Excitation [PDF]

, 2008
A low-cost and externally controlled planar microstrip ferrite phase shifter is designed, where the differential phase shift is considerably improved by introducing circularly polarized electromagnetic waves in the structure.
