Abstract

In this paper, a new ultra-wideband (UWB) antenna is proposed for C-band satellites applications. The main objective of this work is to design an ultra-wideband omnidirectional antenna with a high gain. The proposed antenna is supposed to cover the UWB range from 7.8 GHz to 10.25 GHz for radar applications, and the frequency of 6.3GHz for land stations for satellites. Such a wideband from 7.8 to 10.25GHz is achieved using different slots technologies by etching various shaped slots in the radiating patch. The final antenna has almost invariant radiation properties and reasonable omnidirectional radiation patterns with a gain up to 9.77dB. The antenna is designed on an FR4 substrate with dimensions of (40 × 40 ×1.6mm³). The details of the simulated and measured results for reflection coefficient, gain surface Current distributions and radiation patterns are presented and discussed.
