In this paper, the authors present the design of a novel wideband gap coupled sectoral antenna for communication systems. The circular patch is placed in the aperture of four sectoral rings. The antenna parameters are optimized using various simulations to attain good return loss and corresponding resonant frequency. The antenna operates in X-band at 10.35GHz showing wideband characteristics along with high directivity and reduced side lobe level to a good extent. The antenna has also been studied using Fuzzy Inference System (FIS). The return loss and analogous frequency obtained from simulated results and fuzzy system are compared and in good agreement.
