摘　　要：给出了一种处理宽带天线双端匹配的改进实频法 .该方法将匹配网络输入阻抗的实部近似用对数坐标中的若干直线段表示 ,简化了相位函数的计算 ,降低了功率增益传输函数的非线性 .结合实际天线进行了宽带匹配网络的设计和计算 。A new method--line segment solution is presented to deal with broadband double matching. The real part of impedance of matching network is represented approximately by a number of straight line segments on logarithm coordinate, so that greatly simplifies the calculation of phase function and reduces the degree of nonlinearity of transduce power gain. Finally, by using the measured input impedance data of some antennas given in this paper, the design of those broadband matching network are accomplished.
