1) A 90° degree corner reflector, in conjunction
with a /2 dipole feed, is used in a radar
tracking system. One of the requirements for
such a system is that the antenna, in one of its
modes of operation, has a null along the
forward symmetry axis. To accomplish this,
what should be the feed spacing from the
vertex (in wavelengths)? Give all the possible
values of the feed-to-vertex spacing.
