摘要: In this paper, we propose a new band-notched tapered monopole antenna for ultra-wideband applications. The structure is etched on 1 mm-FR4 epoxy substrate with dielectric constant er = 4.4. ground plane and radiating patch are to obtain good wide impedance matching performance. Inserting two slots in the causes greatly widen bandwidth. By embedding folded trapezoid an inner hole of patch, band-notch function can be achieved. fabricated has small size 18 mm × 20 operates over frequency band between 3 13 GHz VSWR < 2, rejecting undesired from 5.1 5.85 GHz.
