Abstract

A novel compact ultra-wideband (UWB) wide slot antenna with via holes is presented for UWB applications. The antenna is composed of a trapezoidal slot on the ground plane, a rectangular patch in the center of the slot and three via holes connecting the rectangular patch and the microstrip feed-line. The antenna is successfully designed, implemented, and measured. The measured results show that the proposed antenna with compact size of 27.0 mm×29.0 mm×1.0 mm achieves good performance, such as an impedance matching bandwidth of 111.7% (|S₁₁|≤-10 dB), constant gain and stable radiation patterns over its whole frequency range.
