Typical Design Objective
w High Level Designw A well matched, high performance antenna element
w Present Design Task
w Design a matching circuit for the element,
assume the radiating element has already been designed.w Design Challenges
w Rapid design process which supports investigation ofdesign tradeoffs for the matching circuit(e.g. performance versus size)
w Rapidly repeat this design process to account for futurechanges to the radiating element design.
