Design of coplanar waveguide antenna with improved bandwidth for weather radar application and comparison with microstrip antenna.

The aim of the study is to design and analyze a novel coplanar waveguide (CPW) antenna for 2.9 GHz compared with microstrip antenna. Materials and Methods: The antenna was made using a ring structure that was built on a commercially available FR4 Epoxy (4.4) material flexible substrate with a thickness of 1.6 mm. The sample size is estimated to be 40 using the G Power 80% Results: Simulated and experimental results show that novel coplanar waveguide antenna bandwidth is increased to 6.2 dB at the frequency 2.9 GHz. This antenna has been designed and analysed with the aid of Ansoft HFSS version 13.0 software. The significant difference between the two groups was obtained as p<0.05. Conclusion: The obtained results shows that the novel CPW antenna antenna has significantly improved bandwidth weather radar application compared with microstrip antenna. [ABSTRACT FROM AUTHOR]
