A new miniaturized ultra‐wideband antenna with sufficient dual‐band rejection in WiMAX and WLAN bands is reported. The antenna uses the conventional rectangular patch radiator with built‐in sectorial and Inverted‐U slots to achieve the required dual‐band rejections. A coplanar waveguide feed line has been used to achieve the ultra‐wideband operation. The design has been implemented on 1.6 mm thick FR‐4 substrate. The design size is 20 × 26 mm 2 (0.16 λ L × 0.208 λ L in terms of wavelength). An impedance bandwidth of 2.4 GHz to 10.5 GHz has been achieved. Pass‐band gain of 7 dBi and stop‐band gain of −4 dBi have been achieved. Experimental results agree well with simulated results.
