Design and performance evaluation of handset MIMO antenna prototypes

Abstract

This work presents performance evaluation results for four 2×2 multiple-input-multiple-output (MIMO) prototype antenna configurations with different antenna element spacings and polarization properties. The prototypes are based on a size optimized planar inverted-F antenna (PIFA) element which applies a meander structure etched on the metallic patch. Anechoic and reverberation chamber measurements have verified that the simulated performance translates into the manufactured prototypes. The diversity performance of different prototypes is calculated and compared based on different statistical propagation models. Realistic outdoor MIMO transmission experiments at 2.68 GHz show their suitability for spatial multiplexing transmission.
