A recently designed printed slot antenna is presented that incorporates variable band‐notched function for ultrawideband applications. The band notch of this coplanar waveguide fed antenna is achieved by an M‐shaped slot embedded in the radiating element, so a narrow rejected property in the wireless local area network band (5.15–5.825 GHz) is obtained. The rectangular aperture etched in the square ground plane has a determinative role in antenna's impedance band width (IBW) enhancement, and carefully adjusting it leads to wide IBW that due to simulated results it covers the frequency range 2.58–12.86 GHz with VSWR ≤ 2, which corresponds to a fractional bandwidth of 133% excluding the rejected band around 5.04–6.08 GHz. Numerical and experimental results are presented to understand its behavior. The volume of the proposed antenna is 25 × 25 × 0.8 mm 3 . © 2014 Wiley Periodicals, Inc.
