A Printed Wideband Mimo Antenna System for Gsm1800/1900, Umts, Wlan2450, Lte2300/2500, and GPS Applications

Abstract

Abstract-A low-profile wideband multiple-input-multiple-output (MIMO) antenna is presented. The proposed antenna is suitable for mobile terminals applications as its measured −10 dB bandwidth ranges from 1.56 GHz to 2.77 GHz. The overall antenna efficiency ranges from 68% to 83% over the operating bandwidth. The overall size of the proposed antenna is 60 × 97 × 0.8 mm 3 . A novel isolation structure is employed to achieve isolation range of −26 dB to −16 dB. The radiation patterns are measured, and envelope correlation coefficient is evaluated. The simulated and measured results are in good agreement.

A Miniaturized CSRR Loaded 2-Element MIMO Antenna for LTE Band

“…MIMO is used in many wireless communications systems including ultra-wideband [1], Wireless LAN [2], WiMax [3], LTE [4,5], Ka band [6] and 5G communications [7][8][9][10] for better performance, to reduce cost, to improve the data transfer speed, and to alleviate resource utilization. LTE is used in 4G technology and it uses MIMO technology for the improvement of radio spectrum efficiency, throughput, and handoff capabilities.…”
