Unformatted text preview: em of a half-wave dipole with a diameter of 2 cm operating at 100 MHz? Compare it with its maximum physical cross section area A p looking from a parallel direction. This dipole is used for receiving a plane electromagnetic wave which is polarization matched to the dipole. If the power P L developed on a terminal load which is matched to the input impedance of the dipole is W 10 10 9 − × , what is the electric field intensity E of the plane wave at the position of the dipole? Question 4 A quarter-wave monopole (as shown in the figure below) situated above a perfectly conducting ground plane is excited by a sinusoidal source at its base. Find its radiation pattern, radiation resistance R rm , and maximum directivity D m . h = λ /4 Large conducting plane...
