Abstract :
This paper applies the genetic algorithm, using MECG as the object function, to optimize the time-domain performance of antenna and get a novel UWB time-domain antenna. The MECG of the proposed antenna is 0.45 which suggests a good time-domain performance including pulse radiation and pulse fidelity. The result of simulation indicates that the working broadband of the proposed antenna is 3.5G-12G, practically meeting the requirements in impedance bandwidth of FCC for UWB.
