摘　　要：提出一种利用零阶谐振器实现锥状波束天线带宽展宽的新技术。天线将4个零阶谐振器加载到圆形贴片内,从而引进新的谐振,大大增加天线的带宽。该技术将天线的带宽从4.86%扩展到12.8%。天线增益达到5 dBi,最大辐射方向为36°。该天线具有结构简单、加工容易、剖面低和成本低的优点,在整个频段内具有良好的锥状波束特性,而且波束稳定性良好。A new technique for bandwidth broadening of cone-beam antenna using zero-order resonator is proposed.The antenna loads four zero-order resonators into the circular patch,thereby introducing new resonance and greatly increasing the antenna's bandwidth.The technology extends the antenna's bandwidth from 4.86%to 12.8%.The antenna gain reaches 5 dBi and the maximum radiation direction is 36°.The antenna has the advantages of simple structure,easy machining,low profile and low cost,good cone-shaped beam characteristics in the whole frequency band,and good beam stability.
