Topic 3, analysis of microwave networks
In this topic, we will study the resonator
theory (interactive lecture 1 on Feb 11) because the operation of
most microwave components is based on the resonance phenomenon. Such
examples would include components with reactive elements-based matching
circuits, filters, oscillators, antennas etc. In addition, we will study
the scattering parameters, also called the S-parameters (interactive lecture 2 on Feb 18), that are widely used in analysing the operation of microwave circuits through measurements and/or simulations.
The biggest benefit of the S-parameters is they allow the component or
circuit to be modelled as a "black box" which ease the analysis of the
circuit or the system because we do not need to know the fine details of
the component or circuit inside the black box. The S-parameters are
also a viable tool for "pen & paper" type theoretical analysis and
modelling of microwave components and circuits.
The dedicated intended learning outcomes of Topic 3 are:
- The student can analyse the operation of basic microwave circuits and resonators based on calculations and simulations (AWRDE).
- The student can model and analyse the operation of microwave circuits and resonators with suitable circuit parameters, especially the scattering parameters (S-parameters).
- Series and parallel resonant circuits (Pozar chapter 6.1)
- The scattering matrix (Pozar chapter 4.3)
- The transmission (ABCD) matrix (Pozar chapter 4.4)
Interactive lectures take place on Thu Feb 10 and 17 at 9
Preliminary tasksNOTE: MyCourses maintenance break Wed 9.2.2022 from 17:00 to 19:00, service not in use.
Topic 3 consists of four (4) problems and an extra problem (3.E) from which one can earn three (3) extra points to exercise problems – i.e., it can compensate any skipped exercise problem.
