Thank you!
7. Consider an antenna that radiates 100 W for a current lo = 2.0 A. a. Calculate Rrad b. If the same antenna has an efficiency of 90%, calculate Ross C. How much power would be required from the power source to radiate 100 W? (assume good impedance matching) d. If the directivity of the antenna is 3.75, calculate the antenna gain, G.
