Depending on specification single or combination of multiple technologies (for complex requirements) are used, e.g.:
TECHNOLOGIES
————- Coaxial and all kinds of TEM structures, including multiconductor ones, (TEM)
————- PCB all kinds, e.g.: Suspended Substrate, Microstrip, Coplanar Waveguide (CPW), Coplanar strips (CPS), Stripline, Finline, etc, (qTEM)
————- Suspended substrate stripline (SSS)
————- Waveguide (W/G) (all kinds: rectangular, square, corrugated, waffle iron, circular, elliptical, ridge, etc), (TM, TE, hybrid)
————- High Qu Dielectric Resonators (e.g. pucks/DR, suspended dielectric resonators/pucks)
————- Substrate Integrated Waveguides (SIW)
————- Combline (CL) / Interdigital (ID)
————- Lumped/Discrete elements (LE)
————- Etc
Choice of optimal technology or their combination depends on requirements, frequency range, power handling, insertion loss, etc
Particularly for Waveguide components complete multimode (higher order modes) and resonances analysis are performed to ensure desired frequency response. This is necessary as quite often only dominant mode analysis could lead to degraded or completely useless device.
Similar analysis is performed to necessary extent for other technologies as well (though for w/g one it is essentially important).
