A 100-MHz FM broadcast station uses a 300-transmission line between the transmitter and a tower-mounted half-wave dipole antenna. The antenna impedance is 73. You are asked to design a quarter-wave transformer to match the antenna to the line.
(a) Determine the electrical length and characteristic impedance of the quarter wave section.
(b) If the quarter-wave section is a two-wire line with d_ 2 5 cm, and the spacing between the wires is made of polystyrene with r = 2.6, determine the physical length of the quarter-wave section and the radius of the two wire conductors.
