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. 天线 宽带匹配网络 实频法 网络综合 antenna broadband matching network real frequency method network synthesis TN822.8 国家 8 63计划海洋领域重大项目资助 （818-0 1-0 2 ） 2001-05-01 2021-04-01 5
