Ultra wideband and tri-band antennas for satellite applications at C-, X-, and Ku bands
In this paper, a low-cost compact microstrip ultra wideband antenna for satellite and radar communication systems with filtering properties resulting multiband characteristics is presented. The ultra wideband antenna consists of a modified rectangular radiating element with deformed ground plane which provides a wide bandwidth from 5 to 16 GHz. The U-shaped slots are introduced in the radiating patch to obtain the tri-band frequency response covering C, X and Ku bands separately. The frequency bands achieving are 4.9-7 GHz, 7.92-11.08 GHz and 11.85-15.94 GHz. The proposed antennas are successfully simulated and performed using CST MWs and experimental validation are presented to demonstrate the performance of these antennas.
