A novel miniaturized UWB antenna with four band‐notches

In this article, an effective design method is presented to design a miniaturized UWB antenna with four band‐notches. By carefully integrating C‐shaped slots, L‐shaped open circuit stub, and T‐shaped parasitic strip onto the primitive miniaturized antenna, four band‐notches (VSWR > 2) could be achieved at 3.38–3.65 GHz, 4.95–6.05 GHz, 7.42–7.78 GHz, and 8.1–8.9 GHz to reject WiMAX, WLAN, X‐band satellite communication, and ITU 8 GHz band signals. Simulated and measured results show that this antenna could operate from 3.15–11.1 GHz (VSWR < 2), and maintain omnidirectional directivity patterns at H‐plane. Moreover, the proposed antenna has a very compact size of 18.6 × 22 × 1.5 mm3.
