Implication

Experimental design demonstrates enhanced bandwidth and isolation in a miniaturized fractal antenna, indicating strong potential for ultra-wideband communications.

Key Points

To design and evaluate a miniaturized ultra-wideband multiple-input-multiple-output (MIMO) antenna using self-similar fractal geometry.
Generated two self-similar fractal monopole antenna elements using an iterated function system with a calculated fractal dimension of 1.79.
Introduced a slotted T-shaped ground stub between elements to reduce mutual coupling and improve impedance matching.
Evaluated diversity performance metrics and validated electromagnetic simulations against experimental measurements.
Reduced the metallic conductor area by 29.68% at the second fractal iteration, achieving an overall footprint of 24 × 32 mm².
Produced an impedance bandwidth (S11 < −10 dB) of 9.4 GHz ranging from 3.1 to 12.5 GHz with mutual isolation exceeding 16 dB.
