A New Compact Planar Ultra-wideband Microstrip Patch Antenna

摘要

In this paper, a compact ultra-wideband (UWB) printed monopole antenna is proposed, which is suitable for wide-band communication access systems. A special-shaped radiation patch is used in having a yagi-uda like shape-slot. It occupies a compact volume of 40 x 35 x 0.8 (1120 mm3) including the ground plane. The 10 dB impedance bandwidth of the proposed antenna is from 2.81 GHz to 21.41GHz. The design and optimization has been carried out using the commercial software ANSYS HFSS version 14. The antenna has been designed on a FR-4 substrate having thickness 0.8 mm and dielectric constant 4.4. Good radiation patterns and gains within the operating band have been obtained.
