研究目的
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) using a double negative metamaterial based dual-line split-ring resonator (DLSRR) array.
研究成果
The proposed DNG MTM SRR array effectively reduces mutual coupling in microstrip patch arrays with isolation enhancements of 7.34 dB (measured) and 13.2 dB (simulated) at 10 GHz and 1.575 GHz, respectively, without observable changes in far-field gains and radiation efficiencies. The structure offers a solution for miniaturized antenna arrays with significant mutual coupling reduction.
