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

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.
