A MIMO multi-antenna system of compact double uniform circular array (DUCA) in three dimensional direc-tional frequency non-selective Rayleigh fading channel was analyzed and investigated. Equivalent network model of MIMO multi-antenna array considering MC effect was established. general expressions of correlations were derived and the relationship between correlations with and withou... https://allfixelectricales.shop/product-category/freezer-light-cover/
