Sievenpiper HIS and its influence on antenna correlation

[摘要] \label{sec:abstract}This paper deals with the influence of artificial magnetic conductors (AMC), so-calledSievenpiper High Impedance Surfaces (HIS), on the MIMO and Diversityperformance of a planar linear-polarized 2×2 dipole array in the ISM-band at 2.45 GHz.The characteristic performance criteria such as envelope correlation coefficient, spectral efficiency, MeanEffective Gain (MEG) and Diversity gain of a coupled 2×2 dipole array are investigated.By means of full-wave electromagnetic analysis as well as Monte-Carlo simulations applyingstatistical channel models the characteristic antenna pattern just as the MIMO and Diversityanalysis is performed, respectively. The obtained results show that the application ofSievenpiper High Impedance Surfaces to planar antenna arrays enables good MIMO and Diversityperformance compared to ideal configurations in free-space while offering the design oflow profile antennas with simultaneously enhanced characteristics.
