Design and fabrication of a broadband blade monopole antenna operating in 30 MHz–600 MHz frequency band

Abstract

In this paper, design and fabrication of a blade monopole antenna operating in 30 MHz-600 MHz is presented. Blade antennas are preferred antenna structures in airborne applications due to their light weight and aerodynamic shape. Here, the antenna structure is a blade with an oblique edge which shows the improved impedance bandwidth in comparison to a blade antenna with the same total height and no oblique edge. The antenna is matched to a 50 Ω system with VSWR <; 2 in the range 30 MHz-600 MHz. The antenna pattern is omnidirectional with the maximum gain (G) of 5.6 dBi at 600 MHz and G > 0 dBi in the frequency range 150 MHz-600 MHz.
