A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the :
a. Length of the antenna
b. Current fed to the antenna for the measured Electric field.
c. Power radiated by the antenna.
d. If a transmission line with Zo = 75 ? is connected to the antenna, determine the standing wave ratio.
