Investigation results of mobile communication two-element antenna arrays with different types of decoupling structures have been presented. CAD modeling of the antenna with a decoupling structure has been performed by means of ANSYS HFSS. A number of decoupling structures and their influence on antenna radiation pattern and S-parameters have been investigated. Antennas with the best decoupling structure and without it have been produced, investigated and compared. The evaluation of the spectral efficiency improvement has been presented.
