2.85. A base station is installed near your neighborhood. One of the concerns of the residents liv- ing nearby is the exposure to electromagnetic radiation. The input power inside the transmis- sion line feeding the base station antenna is 100 Watts while the omnidirectional radiation amplitude pattern of the base station antenna can be approximated by U(0, 4) = B, sin(8) 0s0 s 180°,0 < ¢ S 360° where B, is a constant. The characteristic impedance of the transmission line feeding the base station antenna is 75 ohms while the input impedance of the base station antenna is 100 ohms. The radiation (conduction/dielectric) efficiency of the base station antenna is 50%.
