Field Optimization using Segmented Patch Antennas at High Frequencies

Abstract

in recent day’s communication technology has increased in every field where in antenna propagation transmission of signals to the other end is dependent on antennas. This propagation should be appropriate in both the fields as near and far fields for effectively covering which RFIDs are used which abbreviate as radio frequency identification which are considered as reader antenna developed for operating in near and far fields with high frequency band range. Here in this paper segmented loop designed of patch antenna is developed and the fabrication of antenna is done where the frequency range will be 900 MHz approximately with coefficient of reflection as less than 8dB which covers major UHB frequency range of band. It has linearly polarized pattern of radiation which provides gain of 6dBi and the capacity of reading of antenna is from 12-15m for both the applications of near and far field.
