In this article, a double‐printed dipole antenna with band‐notched function for UWB applications is proposed and investigated. The band‐notched characteristic is achieved by inserting two U‐shaped slots on the dipole. Experimental and numerical results show that the proposed antenna meets the requirement of 3.1–10.6 GHz UWB systems with VSWR < 2, while avoiding the interference with the 5 GHz WLAN band. Transmitting antenna transfer function, receiving antenna transfer function, and antenna system function are used to describe the antenna performance. The impulse responses in time domain were calculated using inverse Fourier transform.
