Cover Story: To address the challenges of small antenna gain and narrow frequency range, this study employs a fractal repeating array structure and a double-layer folding antenna design to create a high-gain, flexible, and multi-frequency antenna. Fabricated on a 0.1 mm-thick polyimide substrate, this antenna ingeniously integrates the Minkowski fractal structure as a repeating array unit, combined with the double-layer folding antenna design. The resulting antenna measures a mere 0.04 λ0 × 0.026 λ00 @ 2.4 GHz) and weighs only 4 mg. Moreover, the maximum gains of 1.65 dBi and 4.37 dBi were achieved in two frequency bands. Such remarkable dimensions and excellent performance make it ideal for miniature wireless transmission systems and compact mobile communication devices. View this paper
