Aplikasyon pratik nan kominikasyon san fil, yo nan lòd yo efektivman amelyore efikasite kominikasyon ak diminye pouvwa a D 'antèn, antèn la ap fèt ak radyasyon an nan estrikti a yo konsantre direksyon emi pouvwa a, ki ta soti nan "benefis antèn konsèp". Senpleman mete, refere a yon benefis antèn nan opinyon an antèn nan RF pouvwa nan degre ki nan konsantrasyon nan radyasyon, aparamman, modèl la genyen antèn nan relasyon ak gwo, pi etwat la mas grès ki prensipal yo, ki pi piti mas grès ki nan bò antèn, pi wo a nan genyen, epi estrikti diferan nan antèn lan, modèl li yo se yon gwo diferans.

Practical applications in wireless communications, in order to effectively improve communication effectiveness and reduce the antenna input power, the antenna will be made with the radiation of the structure to focus directional radiated power, which would come out of "antenna gain" concept. Simply put, refers to an antenna gain of the antenna input of RF power to the degree of concentration of radiation, apparently, the antenna gain pattern of relationships with large, the narrower the main lobe, the smaller the antenna side lobe, the higher the gain, and different structures of the antenna, its pattern is a big difference.
