yep its an end of the semester project. BUT, we never learned anything
about impedance matching, so I feel no shame in asking people like
yourself. Thanks for your help.


The shame is your course approaching the topic to the point of
construction without introducing matching! Only the most trivial
designs escape this necessity.


Richard, this may be the intent of the instructor i.e. to have students
learn this on their own.


Hi Dan,

Having been an RF instructor for a number of years, it is a shabby
intent when it impedes the graded deliverable.

Now, if this was in fact a beginning of the semester assignment; then,
yes it would be a commendable side goal. However, with the statement
of the total absence of matching coverage, it suggests a rather myopic
view of antennas. In a course of 16 weeks, its introduction could
hardly consume more than 5%. More could be discussed, certainly; but
this minimum is hardly prohibitive.
