提升天线隔离度之射频装置及无线通讯装置;RADIO-FREQUENCY DEVICE AND WIRELESS COMMUNICATION DEVICE FOR ENHANCING ANTENNA ISOLATION

摘要

一种射频装置，用于一无线通讯装置，该射频装置包含有一天线设置区、一接地元件、一第一天线以及一第二天线。该第一天线包含有一馈入板；一第一辐射体，耦接于该馈入板，并电性连接于该接地元件；以及一金属支臂，电性连接于该接地元件；其中，该第一天线与该第二天线共用该接地元件，该馈入板位于该金属支臂与该第一辐射体之间，该金属支臂用来导引该第二天线所产生的一反射讯号至该金属支臂上，以提升该第一天线与该第二天线之隔离度。; a first radiating element, coupled to the feed-in plate and electrically connected to the grounding unit; and a metal branch, electrically connected to the grounding unit; wherein the grounding unit is shared by the first antenna and the second antenna, the feed-in plate is disposed in between the metal branch and the first radiating element, and the metal branch is used for guiding a reflected signal generated from the second antenna to the metal branch so as to enhance isolations of the first antenna and the second antenna.
