Unformatted text preview: zero at the top of the mast and the earth to be a perfectly conducting plane, determine: a)the effective length of the antenna , b)the maximum field intensity at a distance 160(km) from the antenna , c)the time-average radiated power, d)the radiation resistance. 3.Sketch the polar radiation pattern versus for a thin dipole antenna of total length 2 h =1.25 . Determine the width of the main beam between the first nulls. 4.Derive the expressions for the electromagnetic field in the far zone of a small filamentary loop of radius 'b' carrying a uniform time-harmonic current, i ( t )= I cos t , around its circumference....
