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 ...

Improvement the reflection coefficient of Waveguide-Fed Phased-Array Antenna utilizing Liquid Crystal

Abstract— This work investigates the improvement of the active reflection coefficient of waveguide-fed phased-array antenna using liquid crystal layers. The anisotropy properties of liquid crystal layer can be employed to eliminate blind scan angle and improve the wide angle impedance matching of the waveguide-fed phased array antennas. The authors have expressed the modal analysis of the waveg...

Predictive Assessment for Phased Array Antenna Scheduling

In contrast to traditional parabolic dish antennas which must be mechanically steered to point at satellites, phased array antennas operate by electronically activating subarrays in configurations that can be maneuvered across the surface of the antenna without any physical movement. This leads to many benefits including an increase in capacity from the fact that multiple active areas can be en...

A phased antenna array for surface plasmons.

Surface plasmon polaritons are electromagnetic waves that propagate tightly bound to metal surfaces. The concentration of the electromagnetic field at the surface as well as the short wavelength of surface plasmons enable sensitive detection methods and miniaturization of optics. We present an optical frequency plasmonic analog to the phased antenna array as it is well known in radar technology...
