Aims

It is a course giving a general formation about microwave methods, techniques and measurements. The originality of the microwave frequency range is that the wavelength is of the order of magnitude of the size of the devices. This optional course presents the fundamentals of microwave engineering and is proposed as the basic course in this domain for the telecommunication and electronic orientations.

After this course the students will be able to :
- calculate the parameters of various microwave transmission lines
- analyse the parameters of various passive circuits
- design basic passive devices, in waveguide and planar technology
- measure S-parameters of 2-port and 4-port microwave devices, using a scalar network analyser
- use adequate active devices in the frequency range of interest
- calculate the link budget of an earth-satellite link, taking into account the antenna, spatio-temporal characteristics of the channel and the various noise components

Content and teaching methods

Contents
- wave formalism and S-parameters
- transmission lines and resonators (planar lines, waveguides)
- passive devices (obstacles, junctions, couplers, filters, non-reciprocal circuits)
- measurement of circuit parameters : reflection, transmission, power and noise
