摘要

    摘要
  • 摘要: 对矿用可穿戴半模衬底集成空腔天线在柱面弯曲情况下的频率特性、阻抗匹配及辐射特性进行了仿真分析，结果表明：天线柱面弯曲导致谐振频率升高，但-10 dB相对带宽基本不变；当辐射开口发生弯曲时，天线阻抗匹配随着弯曲程度增大而逐渐变差；天线柱面弯曲造成正向辐射增益降低、背向辐射增益升高。因此，针对天线在柱面弯曲情况下的应用，应适当增大天线空腔尺寸和导电底面的长度或宽度，并在选择天线放置方向时应保持辐射开口不弯曲。
    Abstract: Frequency characteristics, impedance matching and radiation characteristics of mine-used wearable half-mode substrate-integrated cavity antenna under cylindrical bending condition were simulated. The simulation results show that cylindrical bending of the antenna leads to an increase of resonance frequency, but the relative bandwidth of -10 dB is basically unchanged. When radiation aperture is bent, impedance matching of the antenna becomes worse as curvature increases. Cylindrical bending of the antenna results in decrease of forward radiation gain and increase of backward radiation gain. Therefore, in view of application of the antenna under cylindrical bending, cavity size and length or width of conductive bottom should be appropriately increased, and radiation aperture should be kept unbent when selecting placement direction of the antenna.
