(4c) A N-tum resonant circular lossless loop, antenna. with a uniform current distribution and with a circumference of V10, is fed by a lossless balanced twin-lead transmission line with a characteristic impedance of 100 ohms, Neglecting proximity effects, determine the (4e1) the closest integer number of turns so that the input impedance is nearly 100 ohms; (4c2) the overall efficiency of the antenna (using the mumber of turns obtained in last question).
