Abstract

This paper presents a compact 8 × 8 multiple input multiple output (MIMO) antenna system designed to operate across two wide frequency bands suitable for fifth-generation (5G) and Wireless Local Area Networks (WLAN) applications. Each antenna element comprises a radiator, a feeding line, and defected ground plane. Each radiator consists of an L-shaped strip and a U-shaped strip. To extend the isolation, defected ground structure (DGS) is employed between the antenna elements. The presented antenna operates across three frequency bands: 3.5 GHz (3.3–3.8 GHz), 4.9 GHz (4.8-5 GHz), and 5.7 GHz (5.15-5.85 GHz), exhibiting excellent isolation, surpassing 15 dB in both lower and higher frequency bands. The overall efficiency exceeds 58%, with an ECC value below 0.125. The simulation and measurement results agree well.
