چکیده
In this paper, a 36×36 design of thinned phased array antenna with subarrays is proposed. Binary-genetic learning particle swarm optimization (GLPSO) was used to thinning factor 60 % 65 %, and continuous-GLPSO apply 36 subarray shapes. The RF beam steering range an azimuth/elevation 40°, the sidelobe levels (SLLs) were 26.67 dB 28.43 dB, half-power beamwidths (HPBWs) 4.6° 4.7°. When applied, digital HPBW/2° in direction. SLLs 22.52 22.53 respectively, HPBWs all 3.5°. are simultaneously performed direction by 40°+HPBW/2°, 20.16 21.25 5°.

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 کاملReduction of Side Lobe Level of Thinned Phased Array Antenna using Genetic Algorithm
Thinned phased array antenna is useful for Radar and satellite communications. Main drawback of phased array antenna is generation of side lobes and grating lobes when the beam is titled from broadside direction toward the end-fire direction. This paper reports the optimization of thinned phased array antenna using genetic algorithm (GA). By varying the tilt angle form broadside direction main ...

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...
