Abstract
This paper presents a novel ultra-wideband microstrip planar antenna operating in frequency band of 2.5-40GHz. The design is based on a rectangular shaped microstrip antenna optimized by genetic algorithm. The final structure of antenna consists of a defected ground structure (DGS) and a notched radiating patch with steps. By etching a Chinese character "日" shaped slot and two symmetric wing-shaped slots on the top, and removing two kinds of irregular shape grooves from the bottom, the return loss S11 is under −10dB between 2.5-40GHz, and the relative bandwidth is 176.47%. The simulated results demonstrated that bandwidth of antenna are greatly affected by those structures.
