Design And Characterization Of Microstrip Patch Antenna For Wireless Communication In Ultra Wide Band Uwb

Abstract

Wireless Communication is the fastest growing and most vibrant newlinetechnological areas in the communication field. Wireless newlineCommunication is a method of transmitting information from one point newlineto other, without using any connection like wires, cables or any physical newlinemedium. In a communication system, information is transmitted from newlinetransmitter to receiver that is placed over a limited distance. With the newlinehelp of Wireless Communication, the transmitter and receiver can be newlineplaced anywhere between few meters to few thousand kilometers. newlineMicrostrip patch antenna play important role in wireless newlinecommunication. Microstrip patch antennas are becoming increasingly newlineuseful because they can be printed directly onto a circuit board. newlineMicrostrip antennas are becoming very widespread within the mobile newlinecommunication. Such antennas are low cost, have a low profile and newlineare easily fabricated. newlineThis research presents the design and analysis of the microstrip patch newlineantenna for ultra wide band communication application. Simulation is newlineperformed using the CST microwave studio software. The simulated newlineresults achieved the optimized designs with improved parameter newlineperformance. newlineDesign one is based on the rectangular shape microstrip antenna. It newlineachieves resonant frequency at 5.4 GHz with -24.33 dB return loss. The newlinecalculated bandwidth is 1064 MHz. The value of VSWR is 1.12. The newlinedirectivity and gain of proposed antenna design is 5.45 dBi and 3 dBi newlinerespectively. The second design is based on the Circular Shape based newlineMicrostrip Patch antenna. It achieves two different frequencies 4.7 GHz newlineand 6.7 GHz with -19.55 dB and -23.51dB return loss respectively is newlineobtained. The calculated bandwidth is 890 MHz for band-1 and 2184 newlineMHz for band 2. The directivity and gain of proposed antenna design is newline4.64 dBi and 4.3 dBi respectively. newline newlinevii newline newlineBoth the antenna is small in size and meets the requirement of ultra newlinewide band frequency range communication applications. Therefore newlineboth the design is fulfilling our research objective and makes it suitable newlinefor the current wi
