A novel and efficient parasitic decoupling network (PDN) is proposed for closely coupled antennas in this paper, which provides a new perspective and approach to design DNs based on the parasitic decoupling concept. The PDN is composed of sections of transmission lines (TLs) and reactive components, allowing additional power-traveling paths. With the TL lengths and reactive component reactance being precisely determined, the traveling power from one antenna to another could cancel out the undesired power wave induced by mutual coupling, resulting in the high port isolation. The decoupling theory is rigorously derived with the design procedure of the PDN systematically …

This paper presented the parasitic structure decoupling method and other related approaches to increase the isolation between two closely coupled antennas. The design parameters of the resultant decoupling structures based on the proposed methods can be precisely derived instead of fitted to achieve high antenna isolations. A two-element monopole array is employed as a benchmark to demonstrate the effectiveness of the proposed methods. The simulation results show that good impedance matching and high port isolation could be achieved simultaneously based on the proposed methods.

A compact dual-frequency dipole array is presented for use in base stations operating in the Digital Cellular System (DCS) and Wideband Code Division Multiple Access (WCDMA) bands. The size-miniaturization is realized by utilizing band notch dipole (BND) as array element and artificial magnetic conductor (AMC) as array reflector for reductions in array width and profile height, respectively. Simulation results show that good impedance matching, high antenna isolation, and good radiation performances are achieved simultaneously.
