Abstract

Rectangular wide-slot ceramic Minkowski fractal antenna for radio frequency identification system, relates to a microstrip antenna, providing a radio frequency identification with small size, large bandwidth, low return loss and omnidirectional radiation characteristics Systematic rectangular wide-slot ceramic Minkowski fractal antenna. There is a ceramic substrate, and both sides of the ceramic substrate are provided with silver-plated layers. One side of the ceramic substrate is silver-plated for the Minkowski fractal antenna radiation patch, and the other side of the ceramic substrate is the silver-plated layer for the antenna ground layer. A rectangular wide slot structure is provided, and an antenna feeding point is provided on the Minkowski fractal antenna patch.

Description

technical field [0001] The invention relates to a microstrip antenna, in particular to a rectangular wide-slot ceramic Minkowski fractal antenna for a radio frequency identification system. Background technique [0002] RFID is the abbreviation of Radio Frequency Identification in English. Radio frequency identification technology is a non-contact automatic identification technology realized by radio frequency communication that emerged in the 1990s. RFID tags have the characteristics of small size, large capacity, long life, and reusability. They can support fast reading and writing, non-visual identification, mobile identification, multi-target identification, positioning and long-term tracking management. Combined with other technologies, it can be used in logistics, manufacturing, public information services and other industries to achieve efficient management and operation and reduce costs. With the continuous improvement and maturity of security soft information-rela...
