With the various sizes, models, and performances, the antenna microstrip can be applied on Radio Frequency Identification (RFID) which have advantages on the security data detection but sometimes, this advantage cannot be approved because of misalignment between antenna and reader which usually used linearly or elliptically polarized antenna tag that can make error during detection data. The circularly polarized microstrip antenna should be applied to reduce the misalignment. It was made from substrate on FR-4 Epoxy material with 40 mm×40 mm and microstrip line fed the antenna can be realized and work broadly covers 2.4 GHz frequency and has circular polarization which is obtained from axial ration below 3 dB on 2 up to 2.45 GHz and directivity with omnidirectional based on simulation and measurement result. © 2015 American Scientific Publishers.
