Abstract :
A new top-loaded ultra-wideband antenna covering the 2.4-10.6 GHz impedance bandwidth (VSWR<2.5) and the 2.05-11.6 GHz UWB bandwidth with nearly constant radiated power was introduced. The proposed antenna is a good candidate for backward compatibility of IEEE 802.11g in the 2.4 GHz ISM band, as well as providing an indoor/outdoor ultra-wideband frequency range of 3.1-10.6 GHz. In addition, it can be used for both multi-band OFDM and impulse UWB applications.
