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 inairborne applications due to their light weight and aerodynamic shape. Here, the antenna structure is a blade with an obliqueedge which shows the improved impedance bandwidth incomparison to a blade antenna with the same total height and no oblique edge. The antenna is matched to a 50 Ω system withVSWR < 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.
