摘　　要：提出了一种小型化双频宽带天线,天线结构由基板背面加载矩形贴片和在馈线上刻蚀一段U型槽线组成。天线制作在相对介电常数为4.4的FR4介质基板上。通过三维仿真工具实现了天线的紧凑结构,总尺寸为25 mm×20 mm×0.6 mm。实测天线可以工作在5.8 GHz^11.0 GHz和14.5 GHz^21.5 GHz两个频段,频带内最大增益为4.23 dBi,实测与仿真结果吻合较好。该天线适合于多标准无线通信系统应用。A miniaturized dual-frequency antenna with broad bandwidth is presented.The proposed structure consists of a rectangular patch loaded on the back of the substrate and one U-shaped slotline which is etched on the feed line.The antenna is fabricated on a FR4 substrate with a relative permittivity 4.4.The compact physical sizes(25 mm×20 mm×0.6 mm)of the antenna is obtained using 3-D simulator tools.The measured results demonstrate that the proposed antenna can operate from 5.8 GHz to 11.0 GHz and 14.5 GHz to 21.5 GHz with the maximum gain of 4.23 dBi.A good agreement between the measured results and the simulated ones is observed.The presented antenna is more suitable for the multi-standard wireless communication systems applications.
