The transmission factor from a 20 mm dipole antenna immersed in the human body equivalent liquid (HBEL) and the deionized water to the outside are investigated using the FDTD analysis and the measurement. Both calculated and measured transmission factor using the mixed-mode S-parameter method are shown good agreement. It is observed that the transmission factor increases as the frequency decreases...
Measurement result of dipole antennas in deionized water is compared with numerical analysis. The results of FDTD simulation and measurement are shown good agreement. Maximum transmission coefficient of ™25 dB through the 74 mm thick deionized water was obtained.
Numerical analysis of the near-field power transfer using multi-antennas is performed based on the scattering parameters for an equivalent circuit model of multi-port networks. The transfer power efficiency is derived by using the multi-port scattering parameters. Since the multi-port scattering parameters are easily measured by a vector network analyzer and calculated by a full-wave numerical analysis,...
In this research, an experimental study has been carried out to measure the MIMO performance in LOS and NLOS indoor environment by using a 2 times 2 MIMO system where the MSAA is used as the receiving antenna with different array spacing. The EVM was measured to demonstrate the performance of the MSAA in the MIMO communication systems. It is found that larger array spacing can improve the EVM, and...
