Design and Parametric Study of Monopole Blade Antenna for UHF-Band Aerospace Applications

This paper provides an idea to design a wideband antenna suitable for UHF-band aircraft application. The blade antenna (BA) has been simulated for different elementary parameters using CST simulator. Antenna performance characteristic with the parametric variation of the antenna model have been studied and demonstrated. The simulation results of the designed antenna show 3.18 dBi gain, and 53-degree half power beamwidth (HPBW) over the entire frequency range 0.9 GHz to 2.0 GHz. Further, the designed antenna a very good return loss performance with VSWR <2.2 in the entire frequency band. This antenna can find its application in aircraft GPS navigation system and datalink operation as well.
