<---Striplines are not resonant. There are sections of transmission lines, therefore you can't "dip" them (that is why they're used in the first place in most UHF/VHF solid-state amps, as they're inherently broadband). You're going to need to learn how to read a Smith Chart if you're dealing with 'em.
