Using FR4 type substrate "𝜀r = 4.3, thickness =1.6mm" we present in this study, the reflection coefficient, the radiation pattern, the gain and the reader distance. Tests in tag detection using this antenna array have shown a reader range of more than 2 m.patch antenna, RFID, Reader, SHF, Patch antenna arrays, CST.
