Abstract

unidade de radiação e antena de estação base. este pedido fornece uma unidade de radiação e uma antena de estação base, e relaciona-se ao campo técnico de comunicações. a unidade de radiação compreende um substrato e dois grupos de braços de radiação. cada grupo de braços de radiação inclui dois braços individuais de radiação. cada braço individual de radiação tem pelo menos uma estrutura de desacoplamento. dois braços individuais de radiação do mesmo grupo de braços de radiação são acoplados por meio de uma superfície de radiação. um braço individual de radiação de cada grupo de braços de radiação é localizado na primeira superfície do substrato, e outro braço individual de radiação é localizado na segunda superfície do substrato; ou, os dois braços individuais de radiação em cada grupo de braços de radiação são localizados na mesma superfície do substrato. na unidade de radiação e na antena de estação base fornecidas neste pedido, os dois braços individuais de radiação de cada grupo de braços de radiação são dispostos em duas superfícies do substrato, respectivamente, aumentando, assim, a largura de banda de impedância. ao acoplar os dois braços individuais de radiação no mesmo grupo de braços de radiação por meio da superfície de radiação e ajustar a área de acoplamento, a atenuação de sinais interfrequência é obtida, o efeito de desacoplamento é melhorado, e o problema técnico na tecnologia existente da dificuldade em reduzir o acoplamento mútuo entre bandas de frequência em uma antena de matriz fundida é solucionado.radiation unit and base station antenna. This application provides a radiation unit and a base station antenna, and relates to the technical field of communications. The radiation unit comprises a substrate and two groups of radiation arms. each group of radiation arms includes two individual radiation arms. each individual radiation arm has at least one decoupling structure. two individual radiation arms from the same group of radiation arms are coupled via a radiation surface. an individual radiation arm of each group of radiation arms is located on the first surface of the substrate, and another individual radiation arm is located on the second surface of the substrate; or, the two individual radiation arms in each group of radiation arms are located on the same surface of the substrate. In the radiation unit and base station antenna provided in this application, the two individual radiation arms of each group of radiation arms are arranged on two substrate surfaces respectively, thereby increasing the impedance bandwidth. By coupling the two individual radiation arms into the same group of radiation arms through the radiation surface and adjusting the coupling area, the attenuation of interfrequency signals is achieved, the decoupling effect is improved, and the technical problem in existing technology the difficulty in reducing mutual coupling between frequency bands in a fused array antenna is resolved.
