        Abstract
        In this study a low cost and small size antenna has been designed at 433 MHz for RFID applications. While designing the
antenna we aimed to keep the antenna geometry as small as possible and the productivity as high as possible without
increasing the cost. The operating parameters of the antenna have been simulated with HFSS software. The reflection
coefficient of outcome parameters belonging to the antenna has been compared with the reflection coefficient of similar
antennas designed in the past..
