摘　　要：本文提出1种具有柔性特点的双极化单极子微带天线,该天线由2个水平正交单极子天线单元构成,选用聚酰亚胺(PI)材料作为介质基板。天线的工作频率为2.45 GHz,端口1和端口2的相对带宽均为13.8%(2.30~2.64GHz),且在带宽范围内隔离度大于15dB,天线在2种不同极化工作状态时的方向图均接近理想单极子的辐射方向图。仿真结果表明:天线分别在X轴和Y轴方向进行弯曲时,天线的相对阻抗带宽、增益和方向图均变化不大。所设计的天线具有结构简单、性能稳定的特点。This paper presents a dual-polarization flexible monopole microstrip antenna,which consists of two horizontal orthogonal monopole antenna units.The polyimide(PI)material is chosen as the dielectric substrate.The radiation pattern of the antenna is close to that of an ideal monopole at different polarizations working state.The simulated results show that the S-parameters,gain and directional pattern of the antenna are have a litle change when the antenna is bent in the X-axis or Y-axis directions.The designed antenna has the characteristics of simple structure and stable performance.
