Microwave Optics012-04630F5Slowly slide the Reflector away from the degree plate until the meter reading passes through a maximumand returns to a new minimum. Measure and record h 2, the new distance between the centerof the degree plate and the surface of the Reflector.h 2= _________________________.6 Measure d 1the distance between the center of the degree scale and the Transmitter diode.d 1= _________________________.7 Use your collected data to calculate l, the wavelength of the microwave radiation.l = _________________________.8 Change the distance between the Transmitter and Receiver and repeat your measurements.h 1= _________________________.h 2= _________________________.d 1= _________________________.l = _________________________.Effective Point of Emission ofTransmitter SignalEffective Point of Reception ofTransmitter SignalReceiver5 cm 5 cmTransmitterReceiverFigure 7.3 Transmission and Reception PointsQuestions1 What is the advantage in having the effective transmission and reception points equidistant from thecenter of the degree plate in this experiment?äÿ NOTE: Don’t stand in front of the apparatus while conducting the experiment. Your body acts asa reflector. Therefore, try to stand to one side behind the plane of the antenna horn.24
