Theoretical radiation admittance of a large bandwidth flat symmetrical folded dipole
Abstract
A theoretical model, equivalent to several lossy transmission lines acting at quasi TEM mode, is given to explain the bandwidth and the radiation admittance of the flat symmetrical folded dipole. It is deduced that the flat dipole is acting at its third resonance with the largest bandwidth. Theoretical results are in good agreement with experiments realized on a model already used in several arrays of high gain or low sidelobe level.
