Özet

1 mm thick rectangular plastic cards having a dimension of 800 mm x 500 mm have been used as quasi-optical matching unit at X-band frequencies. Varying number of plastic cards were placed in varying positions between transmitting and receiving antennas, and complex S-21 and S-11 parameters were measured for each position in order to calculate transmission and reflection coefficient of designed setup. Obtained results showed that increased number of plastic cards from 1 to 6 resulted in decreasing transmission as expected, but certain number of plastic (5 plastics) at a frequency range of 7 GHz-9 GHz behaves as resonating circuit. Manually adjusted multilayered plastic slots can be atomized as continuous microwave adaptation, and proposed setup is quite understandable by students.
