Abstract(in English) This paper presents a low profile 4 x 4 MIMO bi-directional antenna consisting of two composite antennas mounted on a ground plane. The composite antenna is constructed by stacking a notch antenna and a loop antenna on top of each other and each antenna is fed independently. This antenna is capable of dual polarized radiation patterns pointing in two different directions where the notch antenna produces a horizontally polarized wave in x-axis direction while the loop antenna gives a vertically polarized wave in y-axis direction. The combination of two composite antennas has good isolations between the elements and capable of improving the channel capacity for indoor MIMO base station for Long Term Evolution (LTE) application at frequency 3.5 GHz.
