Abstract：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 micros-trip 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 re-duced from 1.9λ×1.9λ×0.1λto 0.9λ×0.9λ×0.01λto realize 52.1% miniaturization.Finally,the measure-ments show good agreement with the simulated one,which validates the correctness of the design.
