Abstract

Decoupling and matching feeding networks are considerably interested in small wireless terminals to enhance their abilities for MIMO systems. In various proposals of DMFN´s, the feeding networks composed of bridge susceptances and transmission lines are simple. However, this DMFN has only been applied to the limited array with special characteristics. This paper presents general design formulas of the DMFN for the two elements and three elements arrays and fundamental numerical data are presented to assure the validity of the design formulas.
