Abstract

This paper presents a new method of modeling and simulation of a linear dipole antenna for ultra-wideband (UWB) applications. The input impedance of the linear dipole antenna is modeled as a RLC equivalent circuit using vector fitting method, and the input current of antenna is simulated in circuit simulator. Then the radiated far field is calculated from the input current, which is compared to the result obtained by electromagnetic simulation software XFDTD6.0 and the validity of the modeling method is verified. With this equivalent circuit model, UWB transmitters and receivers can be designed in circuit simulators in order to facilitate the co-design of the antenna with the impulse generating circuitry without running separate electromagnetic simulations
