摘要
In this article, a novel design of a printed wide-slot antenna with small size, forklike tuning stub and symmetric structure is. presented and experimentally studied, especially for ultra-wideband (UWB) applications. In this design, by embedding three rectangular notches at the edge of the symmetric polygon-like slot below the microstrip-fed line, and by optimizing the feeding structure, new resonant frequencies are generated and the measured impedance bandwidth is increased up to 134.6 percent, from 2.5 to 12.8 GHz, for a VSWR less than 2. This, optimized antenna has compact dimensions of 35 x 44 mm with a peak antenna gain of approximately 4.7 dBi.
