Preface
This textbook originated in my lecture notes for the “Communication ElectronicsI” undergraduate
coursethatIhaveofferedoverthelastsixyearstothestudentsatTheUniversityofWesternOntario
in LondonOntario,Canada. The bookcoversthe transitionalarea between low frequencyand high
frequencywirelesscircuits.Specifically,itintroducesthe fundamentalphysicalprinciplesrelatedto
theoperationofatypicalwirelessradiocommunicationsystem.
BynomeanshaveIattemptedtotouchuponallthepossibletopicsrelatedtowirelesstransmission
systems. Mostmoderntextbookscovera largenumberoftopicswith relativelylow levelofdetails,
which are usually left as an “exercise to the reader”. In this textbook I have chosen to discuss the
subject in more depth,and thus providedetailed mathematicalderivations,applied approximations,
and analogies. The chosen topics are, in my experience, suitable for a one semester, four hours
per week, senior undergraduateengineering course. My intent was to tell a logical story that flows
smoothlyfromonechaptertothenext,hopingthatthereaderwillfinditeasytofollow.
My main inspiration in writing this book came from my students, who at the beginning of the
semester would always ask: “What do I need to study for this course?”. Having a choice between
writinga textbookthatcoversmanytopicsatahighlevel,ortheonethatcoversfewerfundamental
principlesbutinmoredetail,Ichoosethelatter.Allofthematerialinthisbookisconsideredthebasic
knowledgethatisexpectedtohavebeenacquiredbyaspiringengineersenteringthefieldofwireless

Therefore, the intended audience for this book are, primarily, senior undergraduate engineering
studentspreparingfortheircarriersincommunicationelectronics.Atthesametime,myhopeisthat
graduateengineeringstudentswillfindthisbookausefulreferenceforsomeofthetopicsthathave
been only touched upon in the previousstages of their education,or are explained from a different
pointofview.Finally,the practicingjuniorRF engineersmayfindthisbooka handysourceforthe
