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 mm2 (0.16 λL × 0.208 λL 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.

使用“改进的”矩形贴片的微型超宽带天线,在WiMAX和WLAN频带中具有抑制能力

据报道,一种新型的超小型超宽带天线在WiMAX和WLAN频段具有足够的双频抑制能力。天线使用带有内置扇形和倒U形槽的常规矩形贴片辐射器来实现所需的双频带抑制。共面波导馈线已用于实现超宽带操作。该设计已在1.6 mm厚的FR-4基板上实施。设计尺寸为20×26毫米2(0.16 λ大号 ×0.208 λ大号在波长方面)。已经实现了2.4 GHz至10.5 GHz的阻抗带宽。通带增益为7 dBi,阻带增益为−4 dBi。实验结果与模拟结果吻合良好。
