\2.33 Two half-wave dipole antennas, each with an impedance of 75 N, are connected in parallel through a pair of transmission lines, and the combination is connected to a feed

transmission line, as shown in Fig. P2.33. All lines are 50 Q and lossless. (a) Calculate Zin1, the input impedance of the antenna-terminated line, at the parallel juncture. (b) Combine Zin, and Zin, in parallel to obtain Z, the effective load impedance of the feedline. (c) Calculate Zin of the feedline.
