Abstract :
A printed wide slot antenna fed by a microstrip line with a square patch within the arc-shaped slot is proposed for wideband application. The impedance bandwidth and radiation characteristics of this antenna are studied and improved by optimizing the slot shape and dimensions, resulting in an antenna with a 120% bandwidth for S11 ≤ -10 dB and stable radiation patterns across the whole band.
