Mutual Coupling Reduction between Two Closely Spaced Antennas with a General PMC Symmetry Plane for Mobile Terminals

<div>(a) Simulated <i>S</i>-parameters of the conventional antenna model without the decoupling elements (dot lines with a circle) and the proposed isolation improvement system with the decoupling structure and <i>C</i> = 3 pF (full line) or <i>L</i> = 11 nH (dot line). (b) Isolation (<i>S</i>12/<i>S</i>21) at different <i>L</i> from 11 nH to 27 nH.</div>
