柱形开槽天线
摘要：
一种用于RF通信的天线(100)包括辐射部件(102)，该辐射部件(102)基本上是管式的，以在其内确定空腔(104)。辐射部件(102)由导电材料构成，具有从辐射部件(102)的第一部分(108)延伸到第二部分(110)的非导电槽(106)。阻抗匹配装置(120)通过导体(134)电连接到辐射部件(102)，以使辐射部件(102)的阻抗与信号源的阻抗或者负载的阻抗匹配。可以利用单个导电片形成阻抗匹配装置(120)、导体(134)以及至少部分辐射部件(102)，或者作为单个导电结构模制或者压制它们。
摘要（英）：

An antenna (100) for RF communications. The antenna includes a radiating member (102) which is substantially tubular so as to define a cavity (104) therein. The radiating member (102) is made of a conductive material having a non-conductive slot (106) extending from a first portion (108) of the radiating member (102) to a second portion (110). An impedance matching device (120) is electrically connected to the radiating member (102) via a conductor (134) to match an impedance of the radiating member (102) with an impedance of a signal source or an impedance of a load. The impedance matching device (120), the conductor (134), and at least a portion of the radiating member radiating element (102) can formed from a single conductive sheet, or molded or extruded as a single conductive structure.
