Input Resistance of Electrically Short Not-too-Closely Spaced Multi-Element Monopoles with Uniform Current Distribution

Popis výsledku v původním jazyce

In this paper, we derive an analytical expression for the mutual resistance of two electrically short not-too-closely spaced dipoles with uniform current distribution based on an induced electromotive forces method. We go on to apply the relations for folded dipoles for an investigation of the input resistance of a short multi-element dipole arrangement. It is shown that the factor ranging from N^1.77 to N^1.97 takes into account the increase in input resistance arising from the mutual coupling of N = {2, 3, 4} dipoles when they are spaced within the range from ?0/20 to ?0/5. Thus, even a larger distance between the dipoles than ?0/20, which is usually considered if the term N2 is used, still leads to a significant improvement in radiation resistance.To verify the proposed concept, we compared the results provided by the EM simulation and by measurements on the prototype of an electrically small, winding-connected three-element monopole antenna, which occupies a cylindrical geometry w
