Performance analysis and optimization of a MIMO antenna system based upon hybrid diversity for wireless HDTV camera

In this paper, we investigate on the analysis of antennas positioning on a wireless camera for optimizing spatial and polarisation diversity, and consequently MIMO performances. Different configurations are evaluated considering isolation and correlation coefficients. Theses parameters are determined from either simulated or measured radiation pattern coefficients. The diversity efficiency is optimised considering the small available footprint of the antenna support. A hybrid solution combining spatial and polarization diversities are proposed tanks to an original implementation of miniature wideband dipole antennas.
