Preliminary research on electric-magnetic vibrator combined UWB antenna

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.
