Chapter 14, Problem 14.29P

Signals are transmitted at a 1-m carrier wavelength between two identical half-wave dipole antennas spaced by 1 km. The antennas are oriented such that they are exactly parallel to each other. (a) If the Transmitting antenna radiates 100 W, how much power is dissipated by a matched load at the receiving antenna? (b) Suppose the receiving antenna is rotated by 45 °

while the two antennas remain in the same plane. What is the received power in this case?

Question 3 (a) A television receiver's folded dipole antenna has an impedance of 600 0. If a RG-6 coaxial (75 0) coaxial cable is used, calculate the ratio required to match the cable and the antenna. (b) Figure Q3. (b) shows a beam antenna consisting of a dipole, a reflector, and a director. Design the beam antenna given that it is cut for a frequency of 200 MHz and assuming a velocity coefficient of 0.85. The length of the reflector is 5% more than the length of the dipole and the length of the director is 5% less than the length of the dipole. 0.15 Figure Q3(b)
