Practical novel design component of microstrip patch slot antenna MSPSA for RFID applications

This paper presents and demonstrates the necessity of microstrip patch and slot antennas for RFID applications. Various microstrip patch and slot antennas fed by a feed line designed on a 2.2 permittivity Rogers Duriod substrate are considerably studied and comprehensively analyzed as new and authentic new design approaches antennas. The antennas have been designed using the 3D EM High Frequency Structure Simulator (HFSS) V11. The microstrip patch (MSPA) design 1 provides a total antenna gain of 1.87 dBi, a return loss (S11) of -5.5 dB. while the micro strip patch slot antenna (MSPSA) design 2 have achieved a total antenna gain of 6.017 dBi and a return loss (S11) of -23.8 dB at 865 MHz for 60 mm patch length. The other micro strip patch slot antennas (MSPSA) designs have achieved a total antenna gain of 5.92 dBi, 4.48 dBi and at S11 12 dB, 6.87 dB respectively. Modeling and optimization of the one slot MSPSA design 2 have produced the most optimized results hence the MSPSA design 2 is an attractive antenna solution for RFID applications.
