Abstract
An improved loop coupled YIG resonator has a coupling loop of three sections, a loop section partially encircling a YIG resonator, and two straight end sections. The end sections together with a ground plane enclosing one end of the resonator cavity form a transmission line, the characteristic impedance of which is determined by the distance of the end section above the ground plane. The characteristic impedance is chosen to match the transmission line input to which the coupling loop is connected.
