5G MIMO Antenna with Isolation Effect for Handheld Device Applications

Abstract

This paper proposes an array antenna design with eight antennas. Each antenna element is composed of an inverted F-shaped antenna. In addition to its broadband characteristics, it also includes an isolation design with each other. The frequency bands are 3.3-3.8GHz, 4.5-4.6Ghz, 4.8-4.9GHz, the reflection coefficients of the eight antennas are all less than -10dB, and the coupling effect of these frequency bands are also less than -10dB.
