A rectangle‐shaped aperture antenna for ultra‐wideband (UWB) applications which can prevent the interference problems is presented. By attaching a hollow‐cross‐loop resonator (HCLR), triple‐notched frequency bands centred at 3.5, 5.7 and 8.2 GHz are obtained. The HCLR is loaded in the aperture over the microstrip feedline. The proposed antenna has been successfully simulated and measured. Based on the results, it is shown that the proposed antenna yields an impedance bandwidth of 2.55–12 GHz with a voltage standing wave ratio (VSWR) < 2, except for the triple‐notched bands of 3.15–3.85 GHz (WiMAX band), 5.4–6.1 GHz (WLAN band) and 7.8–9.3 GHz (X‐band satellite communication).
