Planar antenna assembly with impedance matching and reduced user interaction for a RF communication equipment
Abstract:
A planar antenna assembly (AA), for an RF communication module, comprises i) a ground plane (GP) and a feeding circuit (FC) defined on a lace of a printed circuit board (PCB), ii) a feed tab (FT1) and a first shorting tab (ST1) coupled to the feeding circuit (FC) and the ground plane (GP) respectively, and iii) a radiating element (RE) comprising a first part (P1) connected to the feed tab (FT) and first shorting tab (ST1), located in a first plane approximately perpendicular to the ground plane (GP) and in which a slot (SO), comprising opened (OE) and closed (CE) ends, is defined, and a second part (P2) extending approximately perpendicularly from the first part (P1) to be located in a second plane lacing and approximately parallel to the ground plane (GP). The feed tab (FT) and first shorting tab (ST1) are parallel and close to each other and connected to the first part (P1) at a chosen place located at a chosen distance away from the slot opened end (OE) in order to define a chosen input impedance.
Abstract(Chinese):

用于RF通信模块的平面天线组件（AA）包括：i）限定在印刷电路板（PCB）的花边上的接地平面（GP）和馈电电路（FC），ii）馈电片（FT1 ）和分别耦合到馈电电路（FC）和接地平面（GP）的第一短路接头（ST1），以及iii）包括连接到馈电片（FT）的第一部分（P1）的辐射元件（RE） 和第一短路片（ST1），其位于大致垂直于接地平面（GP）的第一平面中，并且其中限定了包括打开（OE）和闭合（CE）端部的狭槽（SO），第二部分 （P2），其从第一部分（P1）大致垂直地延伸，以位于第二平面内，并且大致平行于接地平面（GP）。 进给片（FT）和第一短路片（ST1）平行并彼此靠近，并且在位于距离槽开口端（OE）的选定距离处的选定位置处连接到第一部分（P1），以便 定义所选择的输入阻抗。
