Title:
短距離用途のアンテナデバイス及びそのようなアンテナデバイスの使用方法
Document Type and Number:
Japanese Patent JP6417474
Kind Code:
B2
Abstract:
The invention relates to an antenna device (10) for short-range applications, e.g., RFID, comprising: a bipolar coaxial conductor structure (12) with an internal conductor (14) and an external conductor (16); an antenna signal terminal (22, 24) at a first end of the coaxial conductor structure (12) which is formed by a terminal contact (22) on the internal conductor (14) and a terminal contact (24) on the external conductor (16) to feed in an antenna transmitted signal and feed out an antenna received signal; a terminating impedance (Zterm) at a second end of the coaxial conductor structure (12), which is formed by a dipole (Z) connected to the internal conductor (14) at a terminal contact (28) and to the external conductor (16) at a terminal contact (30), wherein the dipole (Z) comprises at least one capacitor (C) and/or at least one inductance (L), such that when transmitting, a HF alternating current propagating through the internal conductor (14) and reaching the second end of the coaxial conductor structure (12) is coupled with the outside of the external conductor (16) at the second end of the coaxial conductor structure (12). The device (10) according to the invention advantageously has a relatively simple construction, with which a relatively wideband electomagnetic transmission (transmitting and/or receiving) of energy and/or information can be carried out advantageously.
