The influence of the person density on the indoor MIMO channel models is experimentally investigated. The path loss is modeled as a log-distance function adding additional attenuations related to both of the distance and person density. Then, the shadowing, the root mean square delay spread, and the channel capacity are described as normal distributed random variables. Their mean value and the standard...
A complementary antenna for wearable applications is proposed. By introducing a loop-monopole combined structure, unidirectional beam is obtained and the interaction between the antenna and the human body can be potentially mitigated. The antenna's operation principle is analyzed and validated at first. Then, prototypes are designed and measured. When the antenna is placed in free space, an impedance...
In this paper, the efficient analysis of electromagnetic scattering from objects is performed utilizing the characteristic basis function method (CBFM) with the compressed sensing (CS) technique. CBFM generates sets of high-level basis functions, i.e. the characteristic basis function (CBF), defined over macro domains of the object under discussion, to significantly reduce the matrix size and storage...
This paper, a novel half-folded antipodal slot antenna fed by microstrip line is proposed. A half-folded tapered slot and patch-like tuning stub is employed to achieve both wideband and low cross-polarization performance. For comparison, a reference rectangular slot antenna fed by microstrip line is also designed, fabricated and measured. As is reported, the operation bandwidth of this antenna is...
