The simulated and measured results verify the coverage of universal UHF RFID band with an omnidirectional radiation pattern and a long-read range of 15 ft. In addition, the read range for different bending angles and lifetimes of the tag antenna are also demonstrated. Operational principle of an omnidirectional long-range ceramic RFID tag. Several orthogonal dipolar modes, resonating at nearby frequencies falling within the uhf RFID band, ensure a uniform spatial response of the tag. Here, we demonstrate and analyze a miniature omnidirectional tag accessible from all 4π stereo angles with a commercial RFID reader. Our design is based on exploring all three dimensions, which allows achieving close to perfect angular coverage by overlapping several multipole resonances of a structure. A planar and miniature (0.09λ×0.13λ) radio frequency identification (RFID) tag antenna is described whose radiation pattern is near omni-directional in three dimensions, with less than 2.6 dB gain deviation in all directions.
In this article, a one-off seal function radio frequency identification (RFID) tag antenna with an omnidirectional radiation pattern when mounted on a liquid bottle is presented. The RFID tag antenna was pasted into the plastic open cap surface or inserted the clamping inner ring for further enhanced the quality of the liquid bottle seal function.This paper presents a triple-feed RFID tag antenna whose radiation pattern is near omni-directional in three dimensions, and which has less than 3.0 dB gain deviation in all directions.
