The chosen resonance frequency is about 2.45 GHZ. A new design of the patch antenna parameters is calculated using theoretical equations, then verified by a simulation and optimization on CST MWS® software .The obtained results from simulation two antenna array simulations present a good impedance matching, and significant gain for this application.enAntenna; CST; Microwave; Patch; RFID; ReaderArticle
