A compact printed log-periodic dipole antenna (LPDA) with distributed inductive load has been presented in this paper. By adding a stub on the top of each element, the dimension of the LPAD can be reduced by 60%. The antenna has obtained an impedance bandwidth of 10GHz (8GHz-18GHz). According to the simulation results, the designed structure achieves stable radiation patterns throughout the operating...
A new ultra-wideband (UWB) antenna with dual notched bands utilizing a simplified composite right/left-handed (SCRLH) resonator is presented. By tuning the dimension of the SCRLH resonator, dual notched bands with sharp rejection can be achieved at desired frequencies to overcome interference with some already existing standards. The dual notched bands of UWB antenna at 3.5 GHz (WiMax) and 5.8 GHz...
