Compact wideband harmonic suppressed antenna using non-uniform cascaded defected ground structure

This article presents a coplanar waveguide-fed wideband bowtie antenna with harmonic suppression using non-uniform cascaded defected ground structure units.The antenna operates between 2 GHz and 5.4 GHz and harmonics are effectively reduced. Its size is only 0.44×0.48 λ02, λ0 being the free-space wavelength at 2 GHz. Simulation and measurement agree very well. © 2012 Wiley Periodicals, Inc.
