An experimental investigation of handset MIMO antennas with dual-band operation was performed using the data from a radio propagation test in an urban area of Aalborg city in Denmark and an over-the-air test using a spatial fading emulator. It is concluded from the agreement between MIMO characteristics of the both measurements that the emulator is effective in evaluating handset MIMO arrays in the...
Outdoor radio propagation experiments are presented at 2.4 GHz, using a handset MIMO antenna with two monopoles and two planar inverted-F antennas (PIFAs), adjacent to a human phantom in browsing stance. The propagation test was performed in an urban area of a city, which resulted in non line-of-sight (NLOS) situations. In our investigation, the 4-by-4 MIMO and SISO channel capacities for the reception...
This paper presents a basic investigation of the power imbalance problem using a dipole array and a handset MIMO model in a browsing situation. Using channel modeling that includes the effects of 3-dimensional angular spectrum and polarization of incident waves, we carried out a Monte Carlo simulation. From the results obtained in this study, estimates of the reduction in channel capacity for different...
The purpose of this study is to evaluate a handset MIMO antenna under practical use conditions, involving multipath radio wave propagation and the influence of the body of the user. To this end, a Monte Carlo computer simulation has been carried out to investigate the distribution of eigenvalues and channel capacity
An area coverage of 4times4 MIMO-OFDM system was measured in residential home environment at 5 GHz band. A novel spatial scanner was fabricated to suit the needs of measurements in environments with household furniture such as beds, sofa and tables. The coverage was calculated based on a total of 55,000 spatial samples in an area of 150 m2 which includes two rooms, a hallway and living and dining...
