Let us start with an overview of this training and introduce the topics.
Overview
Part 2
Then we give more details of the Chapter 1, this is what you get here for free. We explain RF and microwave, describe what electromagnetic spectrum means and name the different frequency bands that are in use.
RF propagation: Ripples on a pond
Part 3
We explain RF propagation by using the picture of the ripple on a pond.
Definition of RF and microwaves
Part 4
Next is the definition of RF and Microwave while talking about wavelength, typical frequency bands and typical applications.
Electromagnetic frequency spectrum
Part 5
We look into the details of the electromagnetic spectrum and why the size of an antenna matters.
Attenuation of EM waves by atmosphere
Part 6
Another important topic is how does the atmosphere influence an electromagnetic wave and the propagation.
Frequency allocations
Part 7
Who is taking care of all these frequencies.and how is the spectrum allocated.
Microwave frequency bands
Part 8
Different frequency bands have different designations. Unfortunately there is an old and new designation. Let´s check it out.
Distributed not lumped
Part 9
How to use distributed circuits at radio frequencies and what to take into account by using coils or capacitors.
Electric fields
Part 10
More details about the electric field and the field around a wire.
Magnetic fields
Part 11
The magnetic field and the right hand rule for magnetic field and electric current.
Electromagnetic radiation
Part 12
The electromagnetic radiation and how this is useful to build an antenna to propagate a signal through space.
Maxwell's equations for harmonic time dependence
Part 13
The Maxwell’s equations and the new way of mathematics, vector calculus, e.g. to describe the relation between E field and magnetic field.
Plane wave fields
Part 14
The plane wave fields and the relation between magnetic and electric field.
RF wave characteristics
Part 15
Parallels between radio frequency and low frequency as well as common terminology.
Units of power, db and dbm
Part 16
All you need to know about units of power like dB and dBm and where these units come from.
RF history
Part 17
Some words about the RF history starting from the electro magnetism, like Morse code.
Timeline of wireless communications development
Part 18
The timeline of wireless communication is quite short, from wireless telegraphy to mobiles.
Safety issues - exposure
Part 19
Here is review of key aspects and safety to reduce health risk.
Safety issues - sar limits
Part 20
Let us look into RF exposure and a heating effect.
Summary
Part 21
This is the summary and e.g. you should have understood the nature of RF and microwave signals or name the frequency bands.
Final test
Part 22
Here you would go to our final test.
Final words
Part 23
Final words and thanks for your interest in our course.
