Abstract
In this article, an ultra wideband ring antenna with a fractal formation for notch application is presented. The antenna was printed on FR-4 substrate, which was a low cost one with the relative permittivity of 4.4 and thickness of 1.6 mm. The total dimension of antenna was 50 mm × 50 mm. It could be applied as a notch antenna for propagation rejection in IEEE 802.11a for instance by covering were as without conflicting with wireless systems. The prototype antenna presented in this article, has a rejection band at 5–6 GHz and covers the frequency range of 2.1–11 GHz with the VSWR of less than 2. For improvement of the notch frequencies and for obtaining dual notch band characteristic some changes in prototype antenna with a slot at fractal structure have been performed. The final antenna had dual notch band at 2.5 and 5.5 GHz. The current distribution in the notch frequency has been provided. The efficiency has also been checked for the entire frequency band. The maximum antenna gain was achieved between 2–8 dBi. All the simulations were done in HFSS and compared with the experimental results. © 2016 Wiley Periodicals, Inc.
