Abstract: This thesis is focused on the microwave miniature ferroelectric tunable devices. Our electromagnetic field analysis shows how the conductor loss affects the quality factor for spiral resonators with different geometric shapes and dimensions (Chapter 3). Chapter 4 introduces the method of conductor loss subtraction in interdigital capacitor ferroelectric measurement. High temperature superconductor is used in a tunable phase shifter (Chapter 5). In order to take advantages of both the low bias voltage of parallel plate varactor and the ease of fabrication of coplanar varactor, we proposed a novel combo structure. The key fixture of the new varactor is the high resistance DC electrode which has slight reaction on the microwave electromagnetic field and appears to be b transparentb to the microwave field. The idea of the b transparencyb is proven by analytic solutions of the electromagnetic field.
