A 50 cm long wire antenna is centr fed by a source with frequency 60 MHz the source drives a current of .5 Amp (rms value) at the input find
i- the current distribution along the antenna , and the radiated power .
ii- if the sorce is now replaced by another with frequency = 300 MHz , find the new current distribution and the radiated power assuming that the input current remains .5 Amp (rms).
