FIG. 3.

Simulated and measured of the stretchable unbalanced loop antenna within 2.0–2.8 GHz: (a) simulated (blue solid) and measured (red dashed) of the nonstretched antenna; (b) measured of the stretched antenna with 20% -axis (blue solid), 40% -axis (red dashed) and 20% -axis (black dotted), 40% -axis (violet dashdot) elongation. The at 2.4 GHz is marked by a cross on each curve.
