Question

8. A one-turn small circular loop is used as a radiating element for a VHF (f = 100 MHz) communications system. The circumference of the loop is C = 1/20 while the radius of the wire is 1/400. Determine, using a wire conductivity of o = 5.7 x 107 S/m, the (a) input resistance of the wire for a single turn. (b) input reactance of the loop. Is it inductive or capacitive? Be specific. (c) inductance (in henries) or capacitance (in farads) that can be placed in series with the loop at the feed to resonate the antenna at f = 100MHZ; choose the element that will accomplish the desired objective.
