Antenna design and interfaces are some of the most varied and difficult topics
to cover in any one venue, whether it be a book, application note, or classroom
session. Unlike amplifier and filter design that has a relatively limited parameter
set and defined well-defined input and output expectations, antennas, being so dependent
on their operational environment, end up having to be satisfied with a set of trade-offs
that come reasonably close to meeting expectations. Unless you are operating in
a fully controlled environment such as an anechoic chamber, the presence of multipath
alone can break even the best antenna design. The aforementioned amplifier and filters
and most other RF components have the luxury of performing their individual functions
from within the protective safety of some sort of shield from outside influences.
Even with sophisticated optimizations software, antenna design is still largely
a "black art." That, undoubtedly, is why you are here looking for someone to do
the job for you.
