Abstract

Un transpondedor RFID, que comprende una antena (1), que comprende un elemento o elementos radiantes (2), un elemento o elementos radiantes parásitos (3), dicho elemento radiante (2) se hace coincidir para crear un primer vector de polarización para estar excitado. El elemento radiante parásito (3) está dispuesto para barrer alrededor de la antena (1) en la proximidad del elemento radiante (2) de modo que el elemento parásito se extiende en dos lados a todos los lados del elemento radiante (2). El elemento radiante parásito (3) se hace coincidir para crear un segundo vector de polarización para estar excitado, siendo el segundo vector de polarización perpendicular al primer vector de polarización.
