Abstract

AbstractA novel cylindrical dielectric resonator antenna based on Fibonacci series approach is presented in this letter. Because of the presence of major and minor axis, the antenna characteristics resemble an Elliptical DRA. Optimized radius to height ratio (a/h) of the antenna and probe feed at an offset position (x = 10 mm, y = 1 mm) from the center is responsible to excite the orthogonal modes and generate quadrature phase shift in polarization of wave, that is, achieving circular polarization. Impedance bandwidth (|S11| < −10 dB) and 3‐dB axial ratio bandwidth achieved are 106.5% (6.1‐12.6 GHz) and 18.9% (10.6‐12.6 GHz), respectively. Fundamental HE11δ and HE12δ modes are excited at 9.1 and 10.8 GHz resonant frequency respectively and maximum gain attained is 7.6 dBi at 8.7 GHz. Peak radiation efficiency of 90% at 7.2 GHz is attained by the proposed dielectric resonator antennas. This antenna supports C, X, and Ku band applications like satellite communication, amateur radio (10‐10.5 GHz), weather monitoring and so on. Simulated and experimental results are in close agreement for fabricated proposed structure.
