A novel dual‐broadband dielectric resonator antenna (DRA) is presented. The proposed antenna has realised both dual‐band and wideband features by applying the modified Sierpinski structure to the antenna design of the proposed DRA. The measured impedance bandwidths for │S 11 │ < −10 dB are 2.25–2.6 GHz (14.46%) and 3.1–4.1 GHz (27.78%), which can cover the wireless local area network (WLAN, 2.4–2.484 GHz) and the worldwide interoperability for microwave access (WiMAX, 3.4–3.69 GHz) bands. Meanwhile, stable radiation patterns and gains of about 5 and 3.8 dBi at 2.4 and 3.5 GHz, respectively, have been observed.
