Dual band operation using metamaterial structure for Radio Frequency Identification (RFID) system

Abstract

The important functions of Radio Frequency Iden tification (RFID) technology are radiation and detection. So efficient antenna desi g n and fabrication is the unique solution which perform a very crucial role for many applications. The reader and ta g intense are component of the RFID system. In this paper desi g ned has done on RFID antenna for ta g and reader application, which also includes the different types of antenna (UHF application, wideband, multiband antenna) and the g eneral consideration for desi g n, them which are currently used for ta g and reader application. In this paper we proposed a rectan g ular patch antenna and then designed a metamaterial structure on the patch to improve the antenna performance.

Enhancementof gain, bandwidth and directivity of a patch antenna by increasing dielectric layers of the substrate through micromachining technique for RFID application

“…The antenna designed on silicon substrate reduces the fabrication and packaging cost, as the designed antenna on silicon substrate provides compatible with CMOS technology [10]. The bandwidth of a patch antenna is given by equation (1).…”

“…Due to exponential growth of automatic identification (AUID) system in many such as animal tracking, supply chain management, biometry, voice recognition etc., the wireless communication system has given the birth of RFID system to identify any object from any place without any line of sight communication [1][2]. RFID system consists of tag or transponder which is tied to the identified object and the reader which is able to read or read/write data to or from the tag respectively.…”

Design of Micromachining Based Patch Antenna to Enhance Performances for RFID Tag Application

“…Reader may also have USB port to communicate data with another system such as PC in which software are installed to process the data in some sequence manner [3][4][5]. Depending on whether tag has internal power source or not, the RFID tag can be passive or active [6]. RFID tag that has internal battery is referred to as active tag and tag does not have any internal power source are classified as passive tag.…”
