Loaʻa ka Antenna: ʻO ka coefficient loaʻa kahi ʻāpana e ana i ka hoʻololi ʻana o ka ikehu a me nā hiʻohiʻona kuhikuhi o ka antenna. ʻO kāna wehewehe:
ʻO ka huahana o ka huina kuhikuhi a me ka pono antenna i hōʻike ʻia e like me: D ʻo ia ka coefficient kuhikuhi a ʻo ia ka pono antenna. Hiki ke ʻike ʻia ʻoi aku ka kiʻekiʻe o ka huina o nā antenna directional coefficient, ʻoi aku ka kiʻekiʻe o ka coefficient loaʻa. A ʻo kona koʻikoʻi kino: ʻo ka coefficient loaʻa o ka antenna e wehewehe i nā manawa he nui e hoʻonui ai ka antenna i kona mana hoʻopuka i ka kuhikuhi radiation kiʻekiʻe i hoʻohālikelike ʻia i kahi antenna directionless kūpono. Hiki ke hoʻomaopopo nui ʻia ʻo ia ka ratio o kahi antenna kuhikuhi i kahi antenna omnidirectional maikaʻi loa (nona ka radiation e like ma nā ʻaoʻao āpau) e hana ana i kahi hōʻailona o kahi nui ma kekahi wahi ma kahi mamao. Antenna efficiency: Ua wehewehe ʻia ka pono o ka Antenna e like me ka ratio o ka mana radiation antenna i ka mana hoʻokomo.
Hoʻohana ʻia ka pale radiation R o nā antenna maʻamau e hoʻāʻo i ka hiki o nā antennas e hoʻomālamalama i ka mana. ʻO ka pale ʻana o ka radiation o nā antennas he helu virtual i wehewehe ʻia penei: me ka resistor R, i ka wā e hele ai ka manawa e like me ka nui o kēia manawa ma ka antenna, ua like ka mana i nalowale me kona mana radiation. ʻIke loa, ʻo ke kiʻekiʻe o ka pale ʻana i ka radiation he hōʻailona koʻikoʻi e ana i ka hiki ke hoʻoheheʻe ʻia o kahi antenna, ʻo ia hoʻi, ʻoi aku ka nui o ka pale ʻana i ka radiation, ʻoi aku ka ikaika o ka hiki ʻana o ka radiation o ka antenna.
ʻO kā mākou huahana kūʻai maikaʻi loa e uhi i nā ʻano like ʻoleONUhuahana series, me ACONU/ kamaʻilioONU/akamaiONU/ pahuONU, etc. ʻO nā mea a pauONUHiki ke hoʻohana ʻia nā huahana series no nā pono pūnaewele i nā hiʻohiʻona like ʻole.
