摘要: 采用频域分析的方法，对电-磁振子组合型超宽带天线物理特性进行了研究，结果表明：天线中的电振子和磁振子在波的传输和辐射过程中起互补作用，扩展了小尺寸天线的工作频带，提高了天线的辐射效率。还给出了50cm天线的模拟和测量结果：电压驻波比小于3时，天线带宽大于10倍频程，模拟与测量结果基本吻合。Abstract: This paper presents the physical characteristics of the electric-magnetic vibrator combined antenna. By calculating numerically and measuring the input/output character of the antenna in frequency-domain and time-domain, it proves that working-frequency of the miniature antenna is widen, and the radiation-efficiency is promoted by the complement of electronic vibrator and magnetic vibrator in the combined antenna. The frequency bandwidth of the antenna is about 10 octave (110MHz~super 1.1GHz) if volt standing-wave ratio is below 3.
