MILLIMETER-WAVE TIGHTLY-COUPLED PHASED ARRAY WITH INTEGRATED MEMS PHASE SHIFTERS

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

Coupled-Oscillator Phased Array Systems for Millimeter Wave Applications*

An array of oscillators coupled through mutual injection locking on a nearest neighbor basis has the property of automatically adjusting itself to linear phase progression across the array in response to appropriate adjustment of the elements at the edge of the array. This mechanism is well-suited to phase generation for phased array antennas at millimeter wavelengths because it obviates the to...

Waveguide-integrated MEMS-based phase shifter for phased array antenna

This paper investigates a new concept of waveguide-based W-band phase shifters for applications in phased array antennas. The phase-shifters are based on a tuneable bilateral finline bandpass filter with 22 MEMS (microelectromechanical system) switching elements, integrated into a custom-made WR-12 waveguide with a replaceable section, whose performance is also investigated in this paper. The i...

تحلیل و طراحی تغییر دهنده فاز N - بیتی MEMS توزیع شده در باند Ka

Modern microwave and millimeter wave phased array antennas are attractive because of their ability to steer wave beams in space without physically moving the antenna element. A typical phased array antenna may have several thousand elements fed by a phase shifter for every antenna, which can steer the resulting array beam to different directions. Their low loss, low cost and lightweight phase s...
