A 1 / 10 - scale model quasi - fractal rcl - loaded monopole antenna was fabricated and measured, which has a bandwidth ratio of about 10 : 1, with vswr less than 3. 0, calculated system gain greater than - 9. 4db and the efficiency above 14 %
加入寬帶匹配網路后,對其10 : 1的縮比模型天線進行了測試,在全頻率段內駐波系數小於3 ,理論增益大於- 9 . 4db ,效率大於14 % 。However, in hf band, the band of the antennas is narrow, and the input impedance of monopole antenna with limited height undergoes rapid variation with frequency
但是,在hf頻段,有限高無加載單極子天線帶寬相對較窄,輸入阻抗隨頻率劇烈變化,難于和50的同軸饋線匹配。
