摘要:In the present paper, the optimal design of the rectangular patch antenna parameters, excited by a microstrip line having a power port 50 adapted to Ω, are introduced to the requirement of improvement of radiation characteristics namely reflection coefficient, the standing wave ratio (VSWR), the input impedance of the antenna and bandwidth. The design was performed using the simulator HFSS (High Frequency Structure Simulator) based on the resolution of Maxwell's equations for the ticket of the finite element method. The objective of this improved radiation characteristics of the antenna patch is the full performance of this antenna at 0.92 MHz for RFID applications. Simulation results show that the reflection coefficient reaches a level of less -31dB, the standing wave ratio is equal to 1.057, and the bandwidth is about 2.75%.
