The Series-Fed, LOG-Periodic Folded Dipole Array

摘要

The antenna described is a new type of unidirectional, plane-polarized, log-periodic antenna array in which the elements are folded dipoles connected in series with the wires of a feeder. In comparison with similar arrays of straight dipoles, the models tested exhibit smaller maximum width, higher directivity and higher impedance. However, construction of the folded dipole array is considerably more difficult due to the shape and required dimensions of the folded elements. (Author)
