Diversity performance of modurated scattering array antenna

Abstract

The diversity performance of the modurated scattering array antenna (MSAA) with various array spacing is measured in Rayleigh fading environment to investigate experimentally the relation between the array spacing and the diversity performance of the MSAA. A 2-element modulated scattering monopole array antenna with various array spacing which is supposed to be used for mobile handset applications is used as the measurement model. It is found that the diversity performance of the MSAA can be improved by reducing the array spacing as small as about 0.2 wavelength.
