Abstract: This paper presents a tri‐band CPW‐fed two‐element MIMO antenna designed for smart home Internet of Things (IoT) applications. The proposed antenna operates at 1.5, 2.4, and 5.8 GHz, with a wide upper‐band response from 3.84 to 7.14 GHz, covering major IoT, Wi‐Fi, Bluetooth, and sub‐6 GHz wireless systems. The novelty of this work lies in the integrated antenna and compact decoupling design, which simultaneously achieves wideband operation, high isolation, and a small footprint. The antenna shows reflection coefficients better than −15 dB across all operating bands and interelement isolation below −28 dB, ensuring low mutual coupling. The design also provides low envelope correlation, a diversity gain close to 10 dB, and stable radiation characteristics. Measured and simulated results show good agreement. Owing to its compact size, strong isolation, and reliable MIMO performance, the proposed antenna is well‐suited for next‐generation smart home and IoT wireless devices. [ABSTRACT FROM AUTHOR]
