Recently, the body area networks (BAN) is one of the most hot topics in wireless communications. In this paper, the research progress of antennas and propagation for wireless BAN (WBAN) in Southeast University (SEU) is reported. Other than the methods of numerical simulation and statistic measurement, the radiation and propagation characteristics of antenna nearby a human body are analytically studied...
A reflectarray antenna consists of the elements of double-layer rectangular patches with slot loading of different lengths, printed on the upper- and down-surfaces of a single-layer substrate respectively, and suspended over a ground plate is proposed and designed for bandwidth enhancement. It has 15 % bandwidth for -1 dB gain-drop from the peak value, is obviously wider than that of conventional...
The EM radiation and the shielding of PIFA of cellular phone to human head are studied by using the method of finite-difference time-domain (FDTD) In this paper. By compare the results of electric field distribution and special absorption rate (SAR) in the head model with two different shield settings, we know that the electric field and SAR distribution in the head model decreased obviously after...
