01 Feb 2018TL;DR: In this article, a double negative metamaterial based dual-line split-ring resonator (DLSRR) array is proposed to mitigate mutual coupling between coplanar elements of 1 × 2 microstrip patch arrays operating at frequencies of 10 GHz and 1.575 GHz.
Abstract: A double negative metamaterial based dual-line split-ring resonator (DLSRR) array is proposed in this paper to mitigate mutual coupling between coplanar elements of 1 × 2 microstrip patch arrays operating at frequencies of 10 GHz (for X-band Application) and 1.575 GHz (for L-band Application). The edge-to-edge spacing between the patches is 0.2Ao at 10 GHz and 0.1λ 0 at 1.575 GHz. The metamaterial decoupling structure comprises of an array of SRRs connected at the corners by two vertical lines and is introduced in between the elements of 1 × 2 arrays. Simulation results show mutual coupling reductions of 7 dB at 10 GHz and 13.2 dB at 1.575 GHz with no noticeable changes in the gain. The validation of simulation results for the array operating at 10 GHz is done using experimental measurements.
