摘要: In this paper, we propose a new Super Wide Band (SWB) antenna with very large bandwidth. The has rectangular patch, 50 Ω microstrip feed line and partial ground plane three round grooves to enhance the characteristics of designed structure are investigated using high frequency simulator (HFSS) computer simulation technology softwares (CST). achieved percentage bandwidth proposed design return loss RL ≥ 10 dB is over 175%. Promising peak gain good impedance matching omni-directional radiation pattern obtained.
