摘要：
A novel Vivaldi antenna structure is proposed to broaden the bandwidth of the conventional ones. The theory of the equivalent circuit is adopted, and it is deduced that the bandwidth of the antenna can be enhanced by the high chip resistor and short pin in the new structure. An antenna of 62 mm (length) x 70 mm (width) x 0.5 mm (thickness) is designed and fabricated. The measure results show that the bandwidth is 1 similar to 20 GHz (VSWR <= 2), while the gain varies between 0.9 and 7.8 dB. It is indicated that the antenna can be reduced to about a half of the conventional ones.
