Spatial diversity performance of printed dual band antennas for WLAN operations

Dual band monopole diversity antennas for mobile terminals operating in the ISM band under the linear switched combining method are presented. Diversity performance is evaluated by means of the envelope correlation coefficient, the mean effective gain and the effective diversity gain of the two ante...

Description
Summary:Dual band monopole diversity antennas for mobile terminals operating in the ISM band under the linear switched combining method are presented. Diversity performance is evaluated by means of the envelope correlation coefficient, the mean effective gain and the effective diversity gain of the two antennas. Geometries of two and three-branch systems are proposed and investigated. Simulation results include the mentioned key indicators of diversity performance as well as radiation patterns and S-parameters. The proposed configurations achieve satisfactory diversity performance and favorable characteristics such as reduced size, large bandwidth, and different radiation pattern complementarity.
