A High Gain Elliptical Slot Antenna for Lower C-band and X-band Application

Abstract

A novel design of printed CPW-fed planar elliptical slot antenna with transformed circular patch is presented here for dual-band application. The obtained impedance band finds application in lower C-band satellite communication and entire X-band with significant gain. Electromagnetic wave simulator HFSS® is used to simulate the structure and the study of parameter behaviour is carried out. The performance of the proposed antenna in terms of return loss, radiation pattern and gain are analysed. Furthermore, the same structure is designed and simulated with microstrip feed line. An imperial formula in terms of axial length and ellipticity ratio of the elliptical slot is formulated to find the lower edge frequency of impedance bandwidth.
