摘　　要：在超宽频带内,自互补结构平面螺旋天线的输入阻抗值约188.5Ω(满足巴比涅-布克原理);在高斯微分脉冲的激励下,辐射电场波形具有高斯二次微分特性,可用于超宽带通信或雷达系统中。在高斯微分脉冲的激励下,用平面螺旋天线进行了收发天线实验,实验结果显示:天线的S11小于-10dB的频率带宽范围与理论分析输入阻抗保持恒定值的范围一致;方向图的实验结果与理论也比较一致。研究表明平面螺旋天线可作为脉冲天线。The theoretically research indicated that the input impedance of Self-Compensated Planar Equiangular Spiral Antennas(PESA) in the interest bandwidth is 188.5Ω(in good agreement with Babinet-Booker's principle).Experiments are carried out with a PESA excited by a derivative Gauss pulse.The experiment results indicated that input resistance bandwidth is in agreement with the theoretical results,and the direction patterm and the received waveform is also in agreement with the the theoretical results.The result is the PESA can be used as pulse antenna.
