MIMO monopole microstrip antenna for LTE

This paper discuss about a MIMO monopole microstrip antenna for LTE application. The MIMO antennas that are currently commercially available for LTE applications generally only cover a narrowband of LTE frequency. Meanwhile, the antenna to cover wider bandwidth will cost a high price. A MIMO microstrip antenna is proposed to overcome that issue due to its small size compared to other antenna for wider bandwidth so that it could save the cost. Based on the measurement in anechoic chamber, the proposed antenna gives a good performance for frequency of 800–2600 MHz. The MIMO monopole microstrip antenna elements have antenna gain of 2–5 dB and mutual coupling below −20 dB.
