摘要

One design method for impedance matching rectangular microstrip antenna based on the maximum working distance has been proposed in this paper to improve the rationality and sensitivity of antenna. First, analyze the impedance matching principle of tag antenna and tap chip, and then change the matching degree with tag antenna based on the impedance presented by control signal change and ensure that the radiation direction of antenna is with good omnidirectional performance with adoption of the principle of maximum theoretical working distance; second, make structural design for UHF frequency characteristic, confirm the position of microstrip antenna feed point of coaxial feed based on impedance matching and satisfy the demand of RFID different frequency tuning through adjusting square and gap size; finally, make simulation analysis of antenna structure with HFSS three dimensional electromagnetic simulation software and verify the effectiveness of the designed antenna model.
