提出了一款新型平面三频段微带缝隙天线。首先设计了一个由阶梯阻抗辐射贴片构成的宽带天线，然后通过在贴片上开 C 型和 U 型缝隙，引入了两个陷波，实现了三频段天线。所设计三频段微带天线的三个频段的中心频率分别为2.54，3.56以及5.06 GHz。其中，第一频段电压驻波比(VSWR)≤2的阻抗带宽范围为2.32~2.76 GHz，第二频段VSWR≤2的阻抗带宽范围为3.34~3.78 GHz，第三频段VSWR≤2的阻抗带宽范围为3.96~6.16 GHz，天线的尺寸为52 mm ×56 mm×0.813 mm。该天线的频带范围包含了无线局域网(WLAN)和全球微波互联接入(WiMAX)的所有频段。

A planar triple-band microstrip slot antenna was proposed. Firstly, a fundamental wideband miscrostrip antenna was designed by using a stepped-impedance radiation patch, then, two notched bands were introduced into the antenna band by adding a C-shaped slot and an U-shaped slot, the proposed triple-band antenna was achieved. Results show that the three working band centers of 2.32–2.76 GHz, 3.34–3.78 GHz and 3.96–6.16 GHz with VSWR≤ 2 are at 2.54, 3.56 and 5.06 GHz , respectively. These three bands cover all the WLAN and WiMAX operation bands.
