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.
