Abstract

A photonic band gap ceramic Sierpinski fractal antenna used in a radio frequency identification system relates to a microstrip antenna, in particular to a photonic band gap ceramic Sierpinski fractal antenna used in a radio frequency identification system. The invention provides a photonic band gap ceramic Sierpinski fractal antenna which is used in a radio frequency identification system and is characterized by small size, wide bandwidth, low return loss and omnidirectional radiation property. The antenna is provided with a ceramic substrate, both two sides of the ceramic substrate are provided with a silver coating respectively, wherein, the silver coating on one side is a Sierpinski fractal antenna radiation patch, and the silver coating on the other side is an antenna ground plane, the antenna ground plane is provided with a rectangular hole array photonic band gap structure, and antenna feed points are arranged on the Sierpinski fractal antenna radiation patch.

Description

technical field [0001] The invention relates to a microstrip antenna, in particular to a photonic bandgap ceramic Sierpinski 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-related ...
