A dual‐port, tapered‐fed fractal antenna with a partial ground is proposed for effective implementation in portable ultra‐wideband–multiple‐input multiple‐output devices. The array is modeled on a 41 × 71 × 1.57 mm3 dielectric FR4 substrate. Each circular radiator defected with a modified Koch–Snowflake fractal (4th iteration) provides 46.7% size miniaturization. The array yields 14.7 GHz bandwidth (3.3–18 GHz, 138%) by defecting the partial ground and offsetting the tapered feedlines. By embedding an H‐shaped decoupler and plus‐shaped slots in the ground, significant isolation (S21/S12 ≤ −16 dB) is accomplished. Various diversity metrics are investigated and are found to follow their permissible standards. To justify the simulated results, the fabricated array is tested where a favorable match between the results makes it a suitable candidate for high data‐rate wireless applications.
