In this paper, normal mode helical antenna is designed for UHF RFID Tag. The antenna is linearly polarised with operating frequency of 900MHz. In the design, meandered path is formed in the helix shape, over the Rogers RO3010(tm) substrate with permittivity of 10.2. The proposed antenna is verified using HFSS simulation software. The proposed antenna is having bandwidth of 200MHz with the axial ratio of 36.5dB. The volumetric size of the tag is 200mm3 and simulated read range of the proposed tag is 10cm. The proposed antenna is mainly designed for near field applications.
