A circular loop, of loop radius / 30λ and wire radius /1000λ, is used as a transmitting/receiving antenna in a back-pack radio communication system at 10 MHz. The wire of the loop is made of copper with a conductivity of 5.7 × 107 S/m. Assuming the antenna is radiating in free space, determine the (a) radiation resistance of the loop

b) loss resistance of the loop (assume that its value is the same as if the wire were straight)

(d) input impedance

(e) radiation efficiency
