Compact printed monopole antenna suitable for UWB applications has been studied and analyzed. The design procedure of the proposed antenna has been elaborated into five stages, Firstly, the antenna with full ground plane was built, in which shows a narrow band of around 10 GHz. Secondly, the ground plane was optimally cut in order to enhance the antenna bandwidth, this version demonstrates a wide bandwidth from 3.15 GHz to 7.20 GHz. Thirdly, to cover the whole range of the UWB spectrum, a rectangle slot was generated on the micro strip line, this version shows a broad frequency range from 3.15 GHz up to 11 GHz, in which meet the UWB system. However, an electromagnetic interference (EMI) may exist in the UWB spectrum, thus, a simple and effective approach of U-slot was used. The U-slot was printed over the radiating element, in which created a notched band around 6.5 GHz. However, this fixed filtering notch cannot be tuned, therefore, a lumped capacitor was positioned on the best place over the generated U-slot, this makes the introduced rejected band tuned over a broad frequency range from 6.5 GHz up to 5.2 GHz. The results exhibit that the antenna structure may be deemed as an attractive candidate for todays’ smart applications.
