fiddler crab Uca rapax Smith 1870 a slotted line The following twostep procedure has been carried out with a 50 Ωcoaxial slotted line to determine an unknown load impedance 1 A short circuit is placed at the load plane resulting in a standing wave on the line with infinite SWR and sharply defined voltage minima as shown in figure 1a On the arbitrarily positioned scale on the Slotted Line

INTRODUCTION TO TRANSMISSION LINES UC Davis impedance at the end of slotted line can be computed using the usual formulas for measurement with a slotted line or can be accomplished graph ically using a Smith Chart with the noted SWR read ings and shift of the minimum point when the line is shorted Construction of Slotted Line As shown in the below diagram the slatted line consists of a minimum λ2 piece having a slot in its longitude and a circular shape internally The test probe is kept inside the slot in such a way that it is parallel to the electric field and the transmission line Improved Slotted Line Increases Accuracy And Convenience Of 1 Assume the load is 100 j50 connected to a 50 ohm line Find coefficient of reflection mag angle and SWR Is it matched well 2 For a 50 ohm lossless transmission line terminated in a load impedance ZL100 j50 ohm determine the fraction of the average incident power reflected by the load Also what is the signal wavelength on the line can be obtained from 1 2 2 λ l l since λ π β 2 The principles of using the slotted line to measure an unknown impedance is as follows A short load is connected to the end of the slotted line A standing wave pattern is obtained on the line Measure one voltage minimum and record its the slotted line is accurately determined for each stub setting IT a discontinuity is present the linear distance between the stub and the voltage minimum on the slotted line will change with the p0 sition of the standingwave pattern For instance if the discontinuity is n series inductance the length of the line section Oct 28
