| 1. An LC resonator for a voltage controlled oscillator comprising:
an inductive transmission line having end portions and side portions, and
input and output ports connected to at least one of the side portions of said transmission line, wherein
said transmission line is grounded in at least one of the end portions, and wherein
said inductive transmission line comprises a plurality of connection ports that are capable of being connected to each other
or to ground in order to tune the resonance frequency of said LC resonator to a selected frequency band.
