6.1 Coaxial resonators
Metallized tubular ceramics are also referred to as dielectric resonators, thus creating coaxial resonators (fig. 18 ). The cross-section of the tube can be square, which facilitates flat mounting on a substrate, as shown in figure 19 . The resonance modes are of the TEM type with field lines as shown in figure 18 . Such a type of resonator is used when insertion losses are less important than volume reduction; this volume for a given frequency is less than...
