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 ...
متن کاملWaveguide-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...
متن کاملPredictive 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...
متن کاملA 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...
متن کاملOptimization for Spherical Phased Array Antenna
The main feature of the phased array antenna is its ability to control the amplitude and phase excitation of each radiating source in order to form and scan the main beam by electronic control without any mechanical contributions. The phased array is composed of a group of element sources which are distributed and oriented in a linear, two or three dimensional configurations. A comprehensive co...
