In this article, a new configuration of ultra‐wideband (UWB) monopole antenna employs two slot‐type split ring resonators (SRRs) with band‐notched filters in 5‐6 GHz WiMAX/WLAN bands. The UWB antenna consists of the octagonal, heptagonal, and triangular patches. A 50 microstrip feedline is employed to stimulate the monopole antenna. With adjusting the size and the position of two slot‐type SRRs on the ground plane, the UWB antenna produce a single band‐notched and decrease interference with the WiMAX/WLAN bands. The results for VSWR, far‐field H‐ and E‐plane radiation patterns and gain of the proposed antennas are presented and discussed. The radiation area of the design antenna is 24 × 17.4 mm2. The measured results show a good agreement with the simulated results. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2595–2598, 2016
