Abstract :
There are some problems when spatial control schemes such as adaptive arrays and multi-input multi-output (MIMO) systems are applied to mobile terminals because they utilize several antenna elements on minute terminals. An analysis and evaluation of the effect of antenna element patterns on antenna pattern control of an array antenna is presented in this paper. The maximal ratio combining method is utilized as an example of a control method for MIMO systems. It is shown that interference can be adequately suppressed even if the antenna element pattern is not ideal and the element spacing is insufficient.
