中文摘要：

提出了一种小型化宽波束的零阶谐振贴片天线。该天线通过在圆形微带贴片天线四周中心对称的加载蘑菇型零阶谐振结构,将圆形贴片激励的TM01模和蘑菇型贴片激励的ZOR 模叠加,在实现天线小型化的同时展宽了天线的波束。仿真结果表明：设计天线中心频点处的 E面和 H 面半功率波瓣宽度分别为114.7°和144.7°,与原始圆形微带贴片天线相比,新天线 E 面和 H 面的半功率波瓣宽度分别展宽了66.5%和60.1%,谐振频点从14.04 GHz降至7.32 GHz,电尺寸由1.9λ×1.9λ×0.1λ缩减至0.9λ×0.9λ×0.01λ,实现了52.1%的小型化效果,仿真和实测结果取得了一致,验证了设计的正确性。

英文摘要：

In this paper,a novel miniaturized Zeroth order Resonance（ZOR）patch antenna with broad beam width is presented.By inserting a centre-symmetric zeroth order resonance structure around circular micro-strip patch antenna combined the TM01 mode and ZOR mode induced by the circular patch and mushroom patch respectively,miniaturization and broadened beam width are realized simultaneously.The half power beam width of E plane and H plane are 114.7°and 144.7°;respectively,compared with the original microstrip antenna,the E plane and H plane HPBW of the new antenna is greatly broadened by 66.5% and 60. 1%.Meanwhile,the resonant frequency is shifted from 14.04 GHz to 7.32 GHz,and the electric size is reduced from 1.9λ×1.9λ×0.1λ to 0.9λ×0.9λ×0.01λ to realize 52.1% miniaturization.Finally,the measure-ments show good agreement with the simulated one,which validates the correctness of the design.
