Abstract :
A microstrip wide slot antenna with a notched frequency band is proposed. The antenna is with an E-shaped radiation patch and is fed by microstrip line, and to realize the band notching function, an E-shaped slot is cut in the E-shaped radiation patch. The Finite Difference Time Domain method is used in the analysis and the results of the FDTD are essentially in agreement with the experimental results. The antenna shows a low return loss within the UWB frequency band, excepting for the notched band from 4.98 to 5.57 GHz which is assigned to the wireless local area network systems. In addition to small size, the antenna also exhibits stable far-field pattern and omnidirectional radiation characteristics in horizontal plane.
