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.
