One important issue is the antenna design to cover all frequency bands (3.1-10.6 GHz). In most applications, a reduced compact antenna is needed but with several requirements. In this paper, a novel triangle-semicircular planar monopole UWB antenna is presented with a notch filter to avoid the undesirable interferences in ISM (Industrial, Scientific and Medical) band at 5.3 GHz.} }
