Abstract

A small tuneable MIMO antenna module is investigated for possible UMTS mobile applications. The radiators are realized as slotted planar monopoles. The two-element MIMO antenna module occupies a volume of 50.0 × 37. 5 × 1.6 mm³ , and is printed onto a FR4 substrate. Low mutual coupling between the radiators is achieved by means of the addition of a coupling strip to a defected ground plane structure. The effect of tuning the resonant frequency, as well as the operational bandwidth is investigated in simulation which indicates that this antenna system should provide a mutual coupling across the full bandwidth better than -13dB.
