A Novel Wideband Decoupling Network for Two Antennas

Abstract

In this paper, a novel wideband decoupling network (DN) is presented, which consists of two 2-way Wilkinson power dividers (WPDs), three transmission lines, and two reactive components. Rigorous design formulas are presented along with systematic design procedures. The transmission-line lengths and component reactances are precisely calculated to achieve high antenna isolation. Measurement results show that a very wide isolation bandwidth of 23.7% can be achieved after using the proposed DN.
