Directivity and VSWR Enhancement of Microstrip Patch Antenna at 2.45GHz Using Novel Inset Fed Microstrip Line Feed for Bluetooth Communications in Comparison with Coaxial Probe Feed
Abstract
Aim: The main objective of this project is to design a rectangular-shaped microstrip patch antenna at
a frequency of 2.45GHz to enhance the Directivity and VSWR using Inset fed technique in Bluetooth
Communications. Materials & Methods: Microstrip patch antenna with microstrip line feed technique
and Coaxial probe feed technique is used with a sample size of 40. Results: By using HFSS Simulation
Software Gain, Directivity, VSWR and Return Loss of Microstrip patch antenna are improved and
noted in comparison with Coaxial probe feed antenna. The Simulation Results obtained for the
designed antenna are Gain is 2.91dB, Directivity is 6.04dB, Return loss for 2.45GHz, 3.7GHz and
4.5GHz frequencies are -17.1dB, -20.1dB, -17.2dB. VSWR for 2.45GHz, 3.7GHz, 4.5GHz frequencies
are 1.3, 1.2, 1.3. Attained significance accuracy ratio p(<0.05) for Gain and Directivity and p(<0.04)
for return loss and vswr in Statistical Analysis. Conclusion: Performance parameters of Microstrip
Patch antenna with microstrip line feed technique appears to be improved when compared with Coaxial probe feed technique. From the results, the proposed antenna can be used for Bluetooth
Communications and Tri-band applications.
