“…To degrade mutual coupling, various types of electromagnetic band-gap (EBG) have been proposed [4]- [7]. Because size of the cell structure of EBG is not so small, these methods are mainly applicable when substrate is thick, dielectric constant is relatively high and distance between antenna elements is not so close.…”

Abstract. An efficient H-plane mutual coupling reduction method is introduced for very closely placed dual-element microstrip antennas operating at 2.4GHz. A simple coplanar waveguide (CPW) structure is introduced in the ground, energy from one element is guided to another element, artificially generating new kind of mutual coupling current. By optimizing size of CPW structure to achieve purpose that new mutual coupling current cancel out with original existing mutual coupling. More than 36dB isolation (|S 21 |) is achieved with dual-element broadside array that distance is less than 0.024 0 O ( 0 O is free space wavelength).

“…Various methods have been developed to suppress mutual coupling effects, such as electromagnetic band-gap (EBG) structures [3][4][5][6], defected grounded structures (DGSs) [7], inductive loaded microstrip patch antennas [8], a Ushaped microstrip line section inserted between antenna elements [9], and a pattern etched onto the ground plane between antenna elements [10]. However, the effect of edge reflections on the mutual coupling was not considered in those studies.…”

-Mutual coupling between antenna elements of a linear microstrip patch antenna array positioned along the H-plane including the effect of edge reflections is investigated. Simple formulas are presented for the estimation of the grounded dielectric substrate size with minimum mutual coupling. The substrate sizes calculated by these formulas are in good agreement with those obtained by the full-wave simulation and experimental measurement. The substrate size with minimum mutual coupling is a function of the effective dielectric constant for surface waves and the distance between the antenna centers. The substrate size with minimum mutual coupling decreases as the effective dielectric constant for surface waves on a finite grounded dielectric substrate increases.
