Abstract- In this project, a compact flexible multi-band CPW-fed antenna with a 2 × 3 AMC layer is proposed. It operates over two bands, 2.3–2.6 and 5.4–6.6 GHz. The measured results show gain improvements of 321.7% (1.47 → 6.2 dBi) at 2.45 GHz and 207.1% (2.67 → 8.2 dBi) at 5.8 GHz, demonstrating the AMC layer can suppress surface waves and enhance gain, confirming the antenna’s potential for flexible and wearable applications.
