摘　　要：运用同轴天线的原理 ,引入附加阻抗 ,通过同一传输线变压器的不同阻抗变换作用 ,改善天线的阻抗特性 ,展宽细同轴天线的频带 ,同时使天线尺寸大为减小。The impedance characteristics of antennas has been improved, the bandwidth of thin coaxial cable antennas been broadened and the size of antennas been reduced largely by means of the coaxial line theory, entry of additional impedance and different impedance transformations of one transmission line transformer. The theoretical analysis and calculation are conformed by the experiment results given.

关 键 词：同轴天线 附加阻抗 阻抗变换 宽频带
