This paper presents a circuit modeling procedure for Ultra‐wideband (UWB) Tx‐Rx antenna systems based on frequency domain S ‐parameters. The modeling used an existing two‐port network's model consisting of four SPICE analog behavioral modules. The accuracy of the model has been validated by comparing its transient response with the measurement result using an oscillograph. This model can be used for the co‐design of the UWB Tx‐Rx antenna system with transmitters and receivers in circuit simulators. In the study, Tx‐Rx antenna systems using planar bow‐tie antenna and horn antenna with ultra‐wide bandwidths are used as examples. Copyright © 2010 John Wiley & Sons, Ltd.
