In this paper, a simple miniaturized printed antenna for ultra-wideband applications with variable band-notch function is proposed. The presented antenna consists of a square radiating patch and a ground plane with inverted T-shaped slot, which increases the bandwidth of 2.3-11 GHz. Frequency band-stop performance is created by two techniques: Defected Ground Structure (DGS) and shorting pins. The designed antenna has a small size of 17×21×1 mm3 , while showing the band rejection performance in the frequency bands of 3.2 to 3.8 and 5.1 to 5.85 GHz, respectively.
