Title
(EN) Multi-band common-caliber antenna and communication equipment
(ZH) 多频段共口径天线和通信设备
Abstract
(EN) The utility model provides a multi-band common-caliber antenna and a communication device. The multi-band common-caliber antenna comprises a first antenna array, a second antenna array and a reflecting plate, the frequency band of the first antenna array is lower than that of the second antenna array; wherein the first antenna array comprises four first dielectric plates perpendicular to the reflecting plate; every two adjacent first dielectric plates are perpendicular to each other. The first antenna array comprises four butterfly hollow dipole units; the dipole unit comprises two radiation arms, and the two radiation arms are respectively printed on the two adjacent first dielectric plates; the radiation arm comprises a first part and a second part; a first feed branch is arranged on the first dielectric plate; the second part has a set width in a direction perpendicular to the reflecting plate; the second antenna array comprises a plurality of second dielectric plates; any second dielectric plate is provided with four annular coils, and the annular coils are connected with a second feed branch knot. And effects of coexistence of high-frequency and low-frequency antenna arrays and no mutual influence of standing waves are realized.
(ZH) 本申请提供一种多频段共口径天线和通信设备。本申请多频段共口径天线,包括:第一天线阵列、第二天线阵列和反射板;第一天线阵列的频段低于第二天线阵列的频段;其中,第一天线阵列包括四个垂直于反射板的第一介质板;相邻两个第一介质板相互垂直;第一天线阵列包括四个蝶形镂空的偶极子单元;偶极子单元包括两个辐射臂,两个辐射臂分别印刷于相邻的两个第一介质板上;辐射臂包括第一部分和第二部分;在第一介质板上设置有第一馈电枝节;第二部分在垂直于反射板的方向上具有设定宽度;第二天线阵列包括多个第二介质板;任意一个第二介质板上设置有四个环状线圈,环状线圈连接有一个第二馈电枝节。实现高低频天线阵列的共存且驻波互不影响的效果。
