New stub-loaded neutralization network for two-element closely-spaced array using even-odd mode analysis

We propose a new stub-loaded neutralization network for two-element closely-spaced array. The new topology, along with a set of rigorous design formulas, is developed based on the even-odd-mode analysis approach. According to the simulated results, the proposed scheme can achieve good impedance matching and excellent port isolation simultaneously for an arbitrary two-element closely-spaced array.
