【摘要】 本文介绍了新型圆环与同心圆盘组合的双频微带天线。圆环天线设计工作于较低频段f_lr,其工作模式为TM12模。圆盘天线设计工作于较高频段f_hr,其工作模式为TM₁₁模。本文采用非对称双矩形开槽的方法展宽圆环天线的带宽。双频天线工作频率f_lr=2.45 GHz和fhr=5.3 GHz,本文设计案例采用FR4介质基板。测试与仿真结果吻合的很好。更多还原

【Abstract】 A novel dual-band microstrip antenna using an annular ring and a concentric circular disk is proposed. The ring is designed and operated in the TM₁₂ mode which is a first band with its frequency of f_lr, the disk is operated in the TM₁₁ mode which is a second band with its frequency of fhr. Two asymmetrical rectangular slots are used to achieve better bandwidth. Design examples of the dual-band antenna working at frequency of f_lr = 2.45 GHz and f_hr = 5.3 GHz based on FR4 are fabricated. The comparisons of simulated and measured results show good agreements.更多还原
