A novel multiband loaded trapezoidal ring fractal antenna (TRFA) is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The self‐similarity property is applied to the trapezoidal structure and the fractal geometry is achieved by consecutive iterations. The proposed antenna has a compact size of 30 × 30 × 1.6 mm 3 . The antenna is fabricated and tested. The fourth iteration of the proposed TRFA covers the 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands with uniform radiation characteristics and an average gain of 2.20 dBi. © 2014 Wiley Periodicals, Inc.
