2.33 Two half-wave dipole antennas, each with an impedanceof 75 2, are connected in parallel through a pair of transmissionlines, and the combination is connected to a feed transmissionline, as

shown in Fig. P2.33. All lines are 50 2 and lossless. ) Calculate Zim. the input impedance of the antennterminated line, at the parallel juncture. b) Combine Zn and Zin, in parallel to obtain Z, the effective load impedance of the feedline. Calculate Zin of the feedline.
