Slovník pojmůInput impedance of the antenna, radiation impedanceInput impedance of the antenna can be measured at the input port of the antenna. Input impedance consists of the radiation resistance RΣ (when multiplied by the squared input current Ivst2, real radiated power is obtained), of the loss-making resistance Rztr (Rztr Ivst2 equals to the power, which is converted to the heat in the antenna and its surrounding) and of the radiation reactance XΣ (describes the mutual energy exchange between the antenna and the electromagnetic field in its surrounding). Radiation resistance and radiation reactance form the radiation impedance together. Zpět
