3. A makeshift dipole transmitting antenna is constructed as shown below to transmit on the 533 MHz band. The load of this antenna, Z₁ = 150 + 50 j 2 is connected to a 6.1 m, Zo = 50 2 lossless transmission line, RG316, with a velocity factor of 0.67c. Zo length generator antenna Zq CH 2/4 SHIS Insulator This paint should be keep m Cam Co Standard Dipole Construction shunt stub Using the Smith Chart or otherwise: (i) (ii) Find the magnitude and phase angle of the reflection coefficient at the load. [1] Find the VSWR for a monochromatic wave on the line. [1] Find the equivalent wavelength of the load. [1] (iii) (iv) Find the equivalent length of the line in wavelengths. [2] (v) Find the impedance of the line and load as input to the generator. [2] (vi) Estimate the minimum length (in wavelengths) for which the terminated line has a purely resistive effective impedance and the value of that resistance. [2] (vii) Estimate the location and characteristic impedance of a quarter-wave transformer required to match the load to the Zo line. [3] (viii) Estimate the location for a short circuit stub to be inserted. [3] Estimate the length of the stub. [3] (ix) (x) Explain briefly why the short circuit stub is preferred to the quarter-wave transformer even though they both match the load to the line. [2] 2 (2) MIRAA Brad Andr C11D Inne tr Rope
