| 摘 要： | 设计了一款新型的具有陷波特性的超宽带单极子天线。该天线的带宽为3. 1 ~ 12. 0 GHz,通过在矩形辐射贴片上制作出对称的梯形结构、中心加载倒C 形缝隙、矩形开槽,并将窄矩形接地板切除两个边角,制作矩形开槽结构,使得天线在3. 3 ~5. 35 GHz 频段产生陷波特性。该天线结构紧凑,尺寸仅为20 mm×25 mm×1. 0 mm。建立天线模型,并对其进行仿真和优化。研究表明,天线在WiMAX 频段、C 波段、数字微波通信、大容量微波通信和部分WLAN 等多个频段产生良好的陷波特性,且在工作频段内有良好的性能和辐射方向特性。

| Abstract: | A novel ultra-wideband monopole antenna with band-notched characteristics is proposed. With a bandwidthof 3. 1 ~12. 0 GHz, by fabricating symmetric trapezium structure, a reversed C-shaped slot in the center and a rectangularslot on the patch, besides, the narrow rectangular ground with a rectangular slot on one side and two edges are moved, thenotch band of 3. 3 ~5. 35 GHz are obtained. The proposed antenna has a compact volume of 20 mm×25 mm×1. 0 mm. Aprototype is designed, simulated and optimized. Results show that this antenna has nice band-notched characteristics forWiMAX, C band, digital radio system, large capacity microwave communication and partial WLAN band, also good perform-ance and radiation characteristics during its operating frequency band. |
