A25-cm-long, center-fed, wire-type antenna is made of copper wire (nonmagnetic, σcu = 5.8×107 s/m) with a radius of 1 mm. the antenna is excited by a sinusoidal current with an amplitude i0 = 5 a. determine the antenna gain (in db) and the time average power radiated, if the frequency is
(a) 1 mhz,
(b) 0.6 ghz.
(c) at what operating frequency the given antenna is more efficient and what is the ratio (in db) of powers emitted at 0.6 ghz and 1 mhz?
