In this paper, a simple compact ultrawideband (UWB) microstrip slot antenna with triple band notched characteristics is presented. In the proposed antenna, a good impedance matching over a very wide frequency range is achieved by adding two rectangular stubs to the bottom section of the simple rectangular patch. Moreover, by employing an inverted T-shaped stub connected to the ground plane and two U-shaped and ?-shaped slots in the modified patch, triple band notched properties are obtained. This proposed triple band notched antenna with dimensions of 26×26 mm2 has a very wide bandwidth from 2.5 GHz up to 19 GHz, which is about 150% fractional bandwidth of the center frequency. Unlike the most previous works reported in the literature, the triple band notched feature applied in the proposed antenna does not deteriorate the impedance bandwidth at higher frequencies. The radiation results such as gain, efficiency and radiation patterns as well as time domain properties of the proposed antenna show that it can be a good candidate for new super wideband applications.
