A circular loop, of loop radius $?/30$ and wire radius $?/1000$, is used as a transmitting/receiving antenna in a back-pack radio communication system at $15\mathrm{MHz}$. The wire of the loop is made of silver with a conductivity of $6.2\times 10^7\mathrm{S}/\mathrm{m}$. Assuming the antenna is radiating in free space, determine the (a) radiatio nresistan ce of the loop; (5 points) (b) loss resistance of the loop (assume that its value is the same as if the wire were straight); (5 points) (c) input resistance; ( 5 points) (d) input impedance; (5 points) (e) radiation efficiency.
