A N-turn resonant circular loop with a uniform current distribution and with a circumference of f/4 , is fed by a lossless balanced twin-lead transmission line with a characteristic impedance of 300 ohms. Neglecting proximity effects, determine the (a) closest integer number of turns so that the input impedance is nearly 300 ohms; (b) input impedance of the antenna; (c) reflection coefficient; (d) VSWR inside the transmission line.
