3) Two half-wave dipole antennas, each with impedance of 750, are connected in parallel through a pair of transmission lines, and the combination is connected to a feed transmission line as shown below: Zin- 0.32- -0.22 0.22- 75 92 (Antenna) 195 Ω (Antenna) Assume that the pair of transmission lines (blue lines) has a characteristic impedance of 500, and the feed transmission line (red line) has a characteristic impedance of 1000. a. Find the input impedance at 0.32 away from the pair of antennas. b. Assume that a generator with V=250e/T/2 and Zg = 500 is connected at 0.32 away from the pair of antennas. How much average power is delivered to each antenna?

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3. The first support should be installed at the wall. ft ( m) from 4. The second support should be installed at from the wall. ft ( m) 5. The final support should be installed at the wall. ft…
