AntennaPattern
Informationbetweentwowirelessdevicesistransferredviaelectromagneticenergy
radiatedbyoneantennaandreceivedbyanother.Theradiatedpowerofmostantennas
isnotuniforminalldirectionsandhasvaryingintensities.Theradiatedpowerinvarious
directionsiscalledthepatternoftheantenna.Eachantennashouldbemoun
tedsothat
itsdirectionofstrongestradiationintensitypointstowardtheotherantennaor
antennaswithwhichitwillexchangesignals.
Completeantennapatternsarethree‐dimensional,although oftenonlyatwo‐
dimensionalsliceofthepatternisshownwhenalltheantennasofinterestarelocated
inroughlythesamehorizontalplane,alongthegrou
ndratherthanaboveorbelowone
another.
Aslicetakeninahorizontalplanethroughthecenter(orlookingdownonthepattern)is
calledtheazimuthpattern.Aviewfromthesiderevealsaverticalplaneslicecalledthe
elevationpattern.
