Total Multi-port Return Loss (TMRL) or, equivalently, Total Multi-port Reflectance is proposed as a relevant and simple Figure of Merit for multi-port (MIMO) antenna systems. TMRL is a straight-forward extension of the notion of Return Loss to multi-port antennas and suitable as the reference quantity on which to base a unique definition of the bandwidth of a MIMO antenna system. The meaning and application...
A novel multi-band internal antenna configuration has been developed for WiMax-capable cellular phones. The new antenna configuration covers all the WiMax bands with other applications in multi-standard multifunction handsets. It consists of three new wideband antennas, which together can cover the whole band from 470 MHz to 6 GHz. The three antennas may have to be used together or only one or two...
This paper investigates the effective gain of antennas in indoor channels. A metric called instantaneous effective gain is proposed, and a multiple-cluster 3D channel model is used to facilitate the proposed antenna effective gain. In the multiple-cluster channel model, Laplacian and double exponential distribution are utilized to model azimuth and elevation signal power distribution respectively,...
