摘要：Two frequency transposers (5a,5b) receive signals from the antenna amplifier(4) and the secondary winding of a current/voltage transformer (1) in the antenna circuit.The transposers supply in phase and quadrature components (I,Q) to a calculator (7) and
a switch (8) enables measurements to be made first on the antenna and then on areference impedance (9). The ratio of these measurements determines the antennaimpedance
