Abstract :
This paper presents a novel dipole equivalent circuit model exhibiting good impedance fidelity over a bandwidth exceeding five octaves. A pair of transmission line segments duplicates the frequency-impedance periodicity of a dipole making broadband impedance fidelity possible with a minimum number of model components. Optimum model component values are found with the use of a genetic algorithm.
