Question

Find the magnetic field if the electric field radiated by the half-wave dipole is 60mV/m?

(a) 159μA/m

(b) 195μA/m

(c) 159mA/m

(d) 195mA/m

The question was asked by my college professor while I was bunking the class.

My enquiry is from Power Radiation from Half Wave Dipole topic in chapter Antenna Parameters – II of Antennas

Answer 1

Right option is (a) 159μA/m

To elaborate: η=\(\frac{E}{H}\)

⇨ 120π=60m/H

⇨ H = 159μA/m
