The invention discloses a low-sidelobe circular polarized microstrip array antenna applied to an electronic toll collection (ETC) system, wherein the antenna is has a three-layer structure successively including a metal foil, a dielectric substrate and a metal foil. A microstrip feed network and radiation units are arranged on the metal foil on the top of the structure; the radiation units employs a grouping mode in which n radiation units are arranged transversely and two radiation units are… CONTINUE READING
