<p>The reflector has a switch (120) connected to an input (141) of a microwave frequency amplifier (140) and impedance (130) i.e. load, in switching positions. A passive power divider (150) is connected to a transmission/reception antenna (110) e.g. cornet or patch antenna, by an input (151) of the divider and to the switch by an output (152). The divider is connected to an output (142) of the amplifier by another input (153) of the divider and to an equivalent load (160) by another output (154) of the divider. The divider introduces a phase difference of 90 on the latter output. An independent claim is also included for a remote measuring system.</p> |
