Abstract
A variable characteristic impedance microstrip resonator for use in a tunable oscillator circuit, the resonator having relatively high characteristic impedance near its driven end to maximize tuning range and relatively low characteristic impedance near its opposite end to minimize losses and thus optimize sideband noise performance.
