Kugwiritsiridwa ntchito kwa mphamvu kwa RF coaxial connectors kudzachepa pamene ma frequency amawonjezeka. Kusintha kwa ma frequency a transmission signal kumabweretsa kusintha kwa chiwopsezo ndi chiwongolero cha voteji, zomwe zimakhudza mphamvu yotumizira mphamvu ndi zotsatira za khungu. Mwachitsanzo, kugwiritsa ntchito mphamvu kwa cholumikizira cha SMA pa 2GHz ndi pafupifupi 500W, ndipo mphamvu yapakati pa 18GHz ndi yochepera 100W.
Kugwiritsa ntchito mphamvu kotchulidwa pamwambapa kumatanthawuza mphamvu yopitirirabe. Ngati mphamvu yolowera ikugwedezeka, mphamvu yogwiritsira ntchito mphamvu idzakhala yapamwamba. Popeza zifukwa zomwe zili pamwambazi ndizosatsimikizika ndipo zidzakhudzana, palibe njira yomwe ingawerengedwe mwachindunji. Chifukwa chake, index ya mphamvu ya mphamvu nthawi zambiri samaperekedwa kwa zolumikizira payekhapayekha. Pokhapokha mu zisonyezo zaukadaulo za zida za microwave passive monga zolumikizira ndi katundu m'pamene mphamvu yamagetsi ndi pompopompo (zosakwana 5μs) zidzawunikidwa pazida zazikulu zamphamvu.
Dziwani kuti ngati njira yopatsirana sikugwirizana bwino ndipo mafunde oyimilira ndi aakulu kwambiri, mphamvu yonyamula pa cholumikizira ikhoza kukhala yayikulu kuposa mphamvu yolowera. Nthawi zambiri, pazifukwa zachitetezo, mphamvu yonyamulidwa pa cholumikizira sayenera kupitilira 1/2 ya mphamvu yake.
Mafunde osalekeza amapitilira pa axis ya nthawi, pomwe mafunde a pulse sapitilira pa axis ya nthawi. Mwachitsanzo, kuwala kwa dzuŵa kumene timaona kumapitirizabe (kuwala ndi mafunde a electromagnetic wave), koma ngati kuwala kwa m'nyumba mwanu kukayamba kuthwanima, kukhoza kuonedwa monga momwe zimakhalira.
Kuti mudziwe zambiri za antennas, chonde pitani:
