Conformal antenna using Circular Microstrip patches in C band

This paper presents designing of a conformal antenna using a number of Microstrip Circular patches in C band frequency range i.e. 4 GHz to 8 GHz. The designed antenna array comprises of 4 elements with a uniform spacing conformed on a cylindrical surface of radius 42.9799 mm. The analysis is done via MATLAB (Phased Array System Toolbox) and the equivalent design also has been verified using the HFSS 3D simulation tool. Conformal antenna with the bandwidth of 0.4124 GHz, Gain of 3.7697 dB, Return Loss of -16.3353 dB, VSWR <; 2 with Co- Polarization of +27.5 dB and Cross Polarization of +2.5 dB, operating at a frequency of 5.8 GHz is designed. This compact antenna is capable of providing 3600 coverage due to its conformability.
