【摘要】 本文提出了一种结构简单的28 GHz和39 GHz毫米波双频微带贴片天线。通过在矩形贴片上开出纵缝,改变了贴片的TM₂₀模式的电场分布,并在贴片下方利用基片集成波导馈电的缝隙激励TM₁₀与TM₂₀模式从而实现双频工作,并且还具有宽带和低剖面的特点。在基片集成波导缝隙馈电结构中加入双频匹配柱,同时采用领结形的缝隙来增加天线的双频段内的带宽。所提出的天线在23.9～31.1 GHz（相对带宽26.2%）和36.9～43.6GHz（相对带宽为16.6%）实现了S₁₁≤10 dB,增益分别为6.6～7.9 dBi和7.3～8.6 dBi。该天线结构简单、性能高,适用于5G毫米波移动通信。更多还原

【Abstract】 A wideband dual-band millimeter-wave patch antenna has been proposed for 28 GHz and 38 GHz band applications Fed by substrate integrated waveguide proximity-coupled slot.A longitudinal slot is etched on the patch surface to change the original E-field distribution of the TM₂₀ mode,A substrate integrated waveguide（SIW） proximity-coupled slot locating beneath the patch is employed to excite the TM₁₀ mode and TM₂₀ mode and the dualband operating is achieved with wideband and low-profile.Two matching vias were used to achieve the dual-band operating,meanwhile and a bow-tie slot was used to broaden the bandwidth of the antenna.The proposed antenna operates from 23.9 GHz to 31.1 GHz（the relative bandwidth is26.2%） and from 36.9 GHz to 43.6 GHz（the relative bandwidth is16.6%） with S₁₁≤-10 dB and simulated gain ranges 6.6～7.9 dBi and 7.3～8.6 dBi.The proposed patch antenna has a very simple structure and great electrical performance and is a candidate for 5 G millimeterWave applications.更多还原
