Question

(6 pts) Design a single turn circular loop operating at 10 MHz such that the radiationresistance is 0.73 Ohm. You may assume RLresonating capacitor.= 0 and that the antenna is

in parallel with a a) What is the radius of the loop? b) What number of turns of the wire is necessary to match (as closely as possible) a300 Ohm feed line? c) Assume the number of turns given in your answer to part (c). An incident planewave is polarization matched to the antenna and has a power density S =10-6 w/m²-m2.What is the maximum power to the load?
