**broken link removed**, in addition to many others, have used a half-wave resonator as a generic model used towards completion of whatever goal.
For anyone who can't view the paper, it pictures a gap-coupled half-wave resonator with feed lines much narrower than the resonating patch.
The question I have is, what is the purpose of narrower, higher impedance gap-coupled feed lines, coupled to the wider, lower impedance half-wave patch resonator? I understand the point of gap-coupling is to weakly-couple the resonator with other elements of the circuit, thereby increasing Q-factor, but which not use a microstrip patch of the same width and impedance as the feed lines?
Is the transition from higher to lower impedance to increase the magnitude of S11?
