A Hertzian dipole is situated parallel to a corner reflector, which is an arrangement of two plane, perfect conductors at right angles to each other, as shown by the crosssectional view in Figure 9.19.
(a) Locate the image antennas required to satisfy the boundary conditions on the corner reflector surface.
(b) Find and sketch the radiation pattern in the cross-sectional plane.
Design the circuit, using reasonable resistance and current values. - What is the overall differential-mode voltage gain?
The field circuit has a dc voltage of 200 V, and the maximum IF is 10 A. The open-circuit characteristic of this motor is shown in Figure. Answer the following questions about the motor, assuming that it is being supplied by an infinite bu..
