Lè vag fèk ap rantre direksyon an polarization nan direksyon an polarization nan matche ak nan antèn resevwa, siyal la te resevwa yo pral piti, se sa ki, ensidan an nan pèt polarization. Pou egzanp: Lè yon + 45 ° antèn polarize resevwa polarization nan vètikal oswa polarization orizontal, oswa, lè polarization nan antèn vètikal polarization oswa-45 ° + 45 ° polarize vag, elatriye ka, Jenere pèt polarization. Yon antèn sikilè-polarization resevwa yon vag avyon linear polarize, oswa lineyè antèn polarization ak swa vag circuler polarization, se konsa sitiyasyon an, li se tou pèt inevitab nan polarization ka resevwa vag fèk ap rantre ------ mwatye enèji a.

When the incoming wave polarization direction of the polarization direction of the receiving antenna match, the received signal will be small, that is, the occurrence of polarization losses. For example: When a +45 ° polarized antenna receives the vertical polarization or horizontal polarization, or, when the vertically polarized antenna polarization or -45 ° +45 ° polarized wave, etc. case, To generate polarization losses. A circular-polarization antenna to receive a linearly polarized plane wave, or linear polarization antenna with either circularly polarized waves, so the situation, it is also inevitable loss of polarization can receive incoming waves ------ half the energy.
