Eight-Element With H-Shaped Slot Mimo Antenna for 5g Applications

Abstract

An eight-element multiple-input-multiple-output antenna system which consists of Hshaped slot antennas is presented around the handset frame for 5G applications. Each antenna element consists of an H-shaped radiating surface and an L-shaped microstrip feeder. In the frequency bands of 3.4-3.6 GHz and 4.7-5.1 GHz, the isolation is lower than −15 dB by introducing the ladder-shaped defect ground structure. The antenna efficiency is 50%-81%, and the envelope correlation coefficient is lower than 0.02 among antenna elements. The measurement results agree well with the simulation ones, indicating that the proposed antenna can satisfy the requirements of 5G communication.

A Quad Port MIMO Antenna Using Rectangular Dielectric Resonator Antenna Array for Intelligent Transportation System Applications

“…The employment of several antennas at transmitter and receiver also alleviates multipath fading in a richly scattered environment. Microstrip based MIMO antennas [2][3][4][5] have been a popular choice for the research community for the past few decades owing to their low-profile characteristics. Though patch-based MIMO antenna systems are very good candidates in low frequency applications, they suffer from severe conductor loss in high frequency applications, which restricts their usage.…”
