Strain-Insensitive Hierarchically Structured Stretchable Microstrip Antennas for Robust Wireless Communication

Highlights The “ordered-unraveling” of hierarchical structures from mechanical assembly contributes to not only the improved overall stretchability, but also the small resonance shift of the stretchable microstrip antenna upon stretching. The mechanical-electromagnetic properties of stretchable microstrip antennas can be controlled by changing the number of arches in the meshed patch. A double-arched microstrip antenna was demonstrated to communicate wirelessly upon 25% stretching or when being placed on human bodies.
