Application of MIMO antenna systems in future wireless networks is inevitable. Using MIMO systems in wireless networks brings many benefits including improvement of the network reliability, security, data throughput and capacity. However, there are some issues such as cost, complexity and physical size which have prohibited their widespread commercial applications. The proposed three year project oversees the development of a novel millimeter-wave MIMO antenna systems tailored to the needs of emerging commercial wireless communications using multi-antenna systems. This theoretical and experimental research will allow our collaboration team from LRTCS-UQAT, INRS-EMT and UQO long with our industrial partner Télébec, to lead Canadian and worldwide efforts in developing cost-effective, high-performance solutions for the emerging MIMO wireless communication market in underground mines. Specifically, our research effort is directed toward developing and implementing new designs of millimeter-wave antenna arrays for mobile terminals and then their applications to implement experimental MIMO systems with low cost and compact size. Our approach is based on new class of wideband millimetre-wave planar antenna arrays. With this approach, an experimental MIMO antenna system will be implemented using microstrip or CPW technology, which allows integration of the antenna array and the MIMO transceiver on the same board. Therefore our research effort will be directed as follows: (i) Accurate and general millimeter-wave techniques will be developed for the design of planar antennas; (ii) Planar antenna arrays will be designed, fabricated and tested; (iii) Simple and practical MIMO channel models will be developed for investigating the performances of wireless communications using MIMO antenna systems; Experimental MIMO system will be designed, fabricated and implemented. Finally, the new knowledge generated from this project and the training of highly qualified personnel associated to the different stages of this work will certainly contribute to enhance Canada's global competitiveness in high-technology sectors.
