Research output: Contribution to journalArticle


An antenna pattern and efficiency estimation procedure for uniform linear dipole arrays with large mutual coupling is presented. The feed currents for each dipole elements are extracted from S-parameters with antenna arrays being treated as N-port circuit networks. The dipole current is assumed to maintain a sinusoidal distribution even in array environments. The estimated patterns for E-plane and H-plane linear array examples as well as a Yagi-Uda sample confirm the validity of the proposed procedure.
