A transmitter circuit with an antenna shown on the left is transformed to the phasor form as shownon the right. The generator resistance is 50 Q2; the antenna is replaced by its equivalent impedance,Za = Za (f) which is a function of frequency f.TXi(t)+ VR -R,ZaRgV,(t)V. +VaThe antenna impedance has the form: Za (f) = f +(100 – f) j [2] where frequency ismeasured in MHz. The generator phasor voltage is V, = 10 V. The average average powerdelivered to the antenna (or any circuit element) with complex impedance Za is given byPavg = Re (Za)|I]°. At which frequency is the average power delivered to the antennamaximized?

Given data, Generator resistance, Rg = 50 Ω. Zaf=f+100-fj Ω. Vg = 10 V. Pavg.=12ReZaI2.
