Design and Performance Analysis of Conformal Antenna for C Band Wireless Applications

The objective of this paper is to design and performance analysis of split ring resonator loaded conformal antenna on a cylindrical surface. This designed antenna has a frequency range in Microwave C band cover the frequency of 5.0 GHz for wireless applications. The proposed antenna is designed on RT/Duroid substrate having permittivity 2.2 and thickness is 0.254 mm which provides flexibility and fed by coaxial feeding techniques. Split ring resonators are cut on the ground plane and patch for enhancing the antenna gain characteristics. Conformal antennas are very suitable for bedded on any curve geometry and provides almost 360-degree coverage with few limitations. The performance parameters ex: return loss, radiation pattern and gain etc are simulated and measured using the HFSS V.13 software. The designed antenna exhibits return loss near about -27.19 dB and 5.7 dB gain with butterfly radiation pattern. This design can be used for a wide range of applications like Satellite Communication, Airborne communication, Automatic Missile, Radar Communication etc.
