Abstract

A novel method for impedance matching of broadband antenna is presented. The paper evaluates the network input reflectance based on minimum mismatching network. The matching networks are obtained in the form of rational polynomials via the simplified real frequency technique (SRFT).The proposed procedure was demonstrated through its application to the design of fourth-order minimum mismatching network over the frequency band of 28-40MHz. Simulation results showed that the VSWR of the low-pass antenna minimum mismatching network had the advantage of less sensitivity comparing with the unmatched network. It is proved the validity of this approach.
