阻抗匹配
Starting with radio wave propagation mechanism, the indoor depolarization phenomenon is analyzed, and the special antenna requirements of WHAN ( wireless home area network) for polarization, radiation and impedance match are researched.
从电波传播机理出发,分析室内电波的退极化现象,研究WHAN对天线的极化、辐射及阻抗匹配特性的特殊要求。
According to requirements of engineering design, antenna efficiency and broadband impedance match network, conical antenna is defined as unit antenna after comparing the electric apparatus and element forms of cage antenna and conical antenna.
从工程设计角度出发,根据天线效率和宽带阻抗匹配网络要求,在比较笼形和锥形两种天线的电气和结构性能之后,确定锥形天线为单元天线。
