Isolation Enhancement of MIMO Antenna for Wireless Routers in LTE band Applications

R. Dhanalakshmi [3] | A. Sivasankar

Abstract: A compact wireless router multiple-input-multiple output (MIMO) antenna for Long Term Evolution (LTE) 2300 band (2300 2400 MHz) and 2500 band (2500-2690 MHz) applications is proposed. The antenna structure consists of two loop parasitic shorted strips and a slot cut between them. The isolating slot not only reduces the coupling between the two monopole antennas; but also improves the bandwidth and efficiency. Without the usage of any additional coupling elements between closely mounted antennas; the proposed antenna achieves isolation of higher than 20 dB; envelope correlation coefficient (ECC) of less than 0.01 and total efficiencies of higher than 82 %. A prototype antenna was fabricated and tested for experimental verification. Both simulated and measured data are provided.

Keywords: LTE, monopole antenna, meander-monopole antenna, multiple-input-multiple-output MIMO, printed antennas, envelope correlation coefficient ECC, isolation, mutual coupling
