Optimization and improved Bandwidth of Fork shape Microstrip Antenna via Artificial Neural Network /

Abstract

A compact Fork- shaped Microstrip patch antenna with improved bandwidth is presented in this paper. The proposed antenna is design and analysis with dielectric substrate of RT/Duroid 2.2 and substrate thickness 3.17 mm. Antenna resonates at multi band of 7.46 GHz and 4.46 GHz .The proposed antenna isoptimized with ANN model .The comparison between measured, simulated and ANN results for slotted microstrip patch antenna has been discussed. The proposed antenna has been fabricated and tested in laboratory .The measured and simulated results are exhibits good agreement. The proposed antenna achieved 40.34% of bandwidth at centre frequency of 7.46 GHz with VSWR ≤ 2 and gain is 4.09dBi
