【Abstract】 The Fourier transformation treatment is used to analyze current distribution, efficiency and impedance of a loading center fed antenna with different parameters over a broad frequency range. Therefore, many corresponding curves are also provided here. On the basis of these results, a loading center fed antenna in the 6MHz~9MHz with VSWR<3.0 is designed and made. Theoretical results derived here agree well with experimental data. The conclusion made can be widely adopted in concerned antenna experiments and designs. In the end of the work, we analyze the advantages of loading center fed antennas array in the detection of the high frequency ground wave radar.更多还原
