Multiband Micro-strip Antenna For Long Term Evolution MIMO System

Nowadays, there are more and more interests in research on multi-input and multi-output (MIMO) systems in the wireless communication. Since it has the ability to increase the capacity of channel using the spatial properties of multipath, it is necessary to have a number of uncorrelated antennas at each end of the communication link. So it seems to be very essential to design adequate antenna due to use in MIMO systems. As revealed in many literatures, both of nonprinted MIMO antennas such as planar-inverted F antennas (PIFAs) and printed MIMO antennas are proposed. However, among the antennas which are used for MIMO application, printed antennas are more appropriate due to their low cost, easy fabrication, and their capability of easily being integrated to small terminal devices
