摘　　要：根据煤矿井下无线通信和人员实时监控对可穿戴式天线的要求,在半模衬底集成空腔天线的基础上,分析了通过在空腔不同位置添加短接针对谐振频率的影响,并利用可拆卸式的螺丝代替短接针,设计了一种能够实现2.45~3.07GHz多频切换的矿用可穿戴式天线。由导电布、导电缝纫线和皮革衬底组成的天线实物的测试结果与仿真结果一致,验证了该天线设计的可行性。Based on half-mode substrate-integrated cavity antenna,a mine-used frequency-switchable half-mode substrate-integrated cavity antenna was designed considering requirements for underground wireless communication and personnel real-time monitoring.Effect on resonance frequency by adding shorting pin in different positions inside cavity was analyzed.Based on the analysis,capacity of frequencyswitching in band of 2.45-3.07 GHz was realized by installing removable screw through several predesigned holes on the antenna.A prototype of the proposed antenna was fabricated with conductive fabric,conductive threads and leather substrate.The design of the proposed antenna was finally validated by agreement between the simulation and test results.
