Abstract
AbstractA dual band‐notched printed ultra‐wideband monopole antenna is presented, with a modified radiating patch.To generate single and dual band‐notched characteristics, we use two rectangular slots. By properly adjusting the dimensions of these slots two controllable notch resonances are achieved, but also the lower edge frequency of the band is decreased. The measured results show that the proposed dual band‐notched monopole antenna offers a wide bandwidth from 2.5 to 11 GHz, with two notched bands, covering all the 5.2/5.8 GHz wireless local area network, 3.5/5.5‐GHz WiMAX and 4‐GHz C bands. The designed antenna has a small size of 12 × 18 mm2. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:372–374, 2012; View this article online at wileyonlinelibrary.com.
