Abstract

a presente invenção divulga uma antena de corneta (300), incluindo uma superfície seletiva de frequência (fss) (310), uma estrutura de conexão (320) e um tubo de guia de ondas (330). a estrutura de conexão (320) inclui uma primeira placa dielétrica (321), uma segunda placa dielétrica (322) e uma parede dielétrica (323). uma primeira superfície da primeira placa dielétrica (321) é um hiperboloide cuja superfície é protuberante, uma segunda superfície da primeira placa dielétrica (321) é conectada à parede dielétrica (323), e um espaçamento entre as duas superfícies é uma espessura da primeira placa dielétrica (321). a parede dielétrica (323) tem uma estrutura tubular, uma primeira superfície da parede dielétrica (323) é coberta pela primeira placa dielétrica (321), uma segunda superfície da parede dielétrica (323) é coberta pela segunda placa dielétrica (322), e um espaçamento entre as duas superfícies é uma altura da parede dielétrica. existe um orifício na posição média da segunda placa dielétrica (322). a parede dielétrica (323), a primeira placa dielétrica (321) e a segunda placa dielétrica (322) formam em conjunto uma estrutura oca. a fss (310) cobre a primeira superfície da primeira placa dielétrica (321). uma parte do tubo de guia de ondas (330) é inserida no orifício da segunda placa dielétrica (322). a antena de corneta descrita na presente invenção pode reduzir a altura de lóbulo lateral de um feixe transmitido através da fss, melhorar a diretividade da antena, e ainda fornecer maior eficiência de radiação.
