A triple band‐notched UWB monopole antennas is presented for flexible electronics. To enhance the flexibility, ultra‐thin liquid crystal polymer with 50 μm thickness is used as the substrate. The antennas are constituted by swallow tail radiation patch and trapezoid ground. Moreover, band‐notched characteristic is realised by etching different sized elliptic single complementary split‐ring resonators on the radiation patch. An improved triple band‐notched UWB antenna with notched‐frequency bands at 3.7–4.2 GHz, 5.15–5.35 GHz, and 5.725–5.825 GHz are designed by a novel capacitance compensation method. The measured radiation patterns indicate that the antennas are an omni‐directional antenna both at flat and bent circumstances. The occupied area of antenna is 27 × 21 mm.
