초록
A novel flexible zeroth-order resonant (ZOR) antenna is proposed. Its zero phase constant ensures that the antenna performance is independent of substrate deformation. A composite right/left-handed transmission line is designed based on coplanar waveguide technology to realise the zeroth-order resonance phenomenon. This provides good performance: reasonable bandwidth (6.5) and peak gain (0.69-1.39dBi). Simulated and measured results show that the antenna's resonant frequencies and radiation patterns are almost unchanged at different curvature diameters of 30, 50, 70mm, as well as for a flat surface. It is belived that this is the first reported ZOR antenna on a flexible substrate. © 2010 The Institution of Engineering and Technology.
