Abstract

A microstrip antenna includes: a radiation sheet; a grounding plate parallel to the radiation sheet; a short-circuit sheet conductively connected with the radiation sheet and the grounding plate; and a feed sheet positioned between the radiation sheet and the grounding plate; wherein the radiation sheet is provided with a slit so that the radiation sheet is U-shaped as a whole, and the U-shapedradiation sheet comprises two sub-sheets forming two arms of the U-shaped radiation sheet and a connecting part forming the bottom edge of the U-shaped radiation sheet; a feed source is arranged in the slit, one of a positive electrode and a negative electrode of the feed source is electrically connected with the connecting part, and the other one of the positive electrode and the negative electrode of the feed source is electrically connected with the feed sheet through a feed line; wherein the bottom side of the feed sheet is arranged to cling to the grounding plate and is separated from thegrounding plate through an insulating film, and the thickness of the insulating film is far less than 1/4 wavelength corresponding to the resonant frequency of the microstrip antenna. The microstripantenna provided by the invention is easy to realize mass production and keep consistent performance, has good metal resistance, is easy to adjust, and can be adapted to different frequency band requirements of different countries and regions in a simple manner.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a microstrip antenna, an electronic tag with anti-metal function and a manufacturing method of the electronic tag. Background technique [0002] Nowadays, more and more commodities are included in the Internet of Things system, and the use of electronic tags is becoming more and more extensive. At present, the cheapest electronic tags are ultra-high frequency electronic tags that work at UHF (Ultra High Frequency) frequency. The UHF RFID frequency band applicable to Europe is the ETSI frequency band (865-868MHz), and the UHF RFID frequency band applicable to the United States. The RFID frequency band is the FCC frequency band (902-928MHz), and its main frequency in China is 915MHz. Different from the previous two generations of 125KHz and 13.56MHz magnetic induction coupling data transmission, UHF RFID adopts the direct transmission of electromagnetic waves simila...
