Embodiment Construction

[0029] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0030] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a RFID reader and a reading antenna thereof. The RFID reader comprises a circuit board, an antenna oscillator and a reflective oscillator, wherein the circuit board comprisesa signal layer, a ground layer and a reflective layer which are arranged in a lamination way, the ground layer and the reflective layer are arranged at the same side of the signal layer, the signal layer is provided with a transmission line, the ground layer is provided with a ground wire, the antenna oscillator comprises two resonant arms, the two resonant arms are respectively arranged at the signal layer and the ground layer, each resonant arm is provided with a feeding end and a radiation tail end, the feeding ends of the two resonant arms are respectively and electrically connected with the transmission line and the ground wire, the projections of the two resonant arms on the reflective layer are in axial symmetry, the reflective oscillator is arranged at the reflective layer, and theprojections of the reflective oscillator and the antenna oscillator on the reflective layer are opposite to each other. The RFID reader and the reading antenna thereof, provided by the invention, have the characteristic that the RFID reader and the reading antenna thereof are convenient to use.

Description

technical field [0001] The invention relates to the field of radio technology, in particular to an RFID reader-writer and its read-write antenna. Background technique [0002] The RFID reader is a radio frequency identification reader, which includes an RFID read-write antenna inside. An RFID read-write antenna refers to an antenna that identifies a specific target and obtains relevant data by sending or receiving radio signals. The RFID read-write antenna does not need to establish mechanical or optical contact between the identification system and a specific target, without manual intervention, and the operation is fast and convenient. RFID read-write antennas are currently widely used in logistics, anti-counterfeiting traceability, ETC, etc. [0003] Antenna gain refers to the ratio of the power density of the signal generated at the same point in the space between the actual antenna and the ideal radiating element under the condition of equal input power. The higher t...
