omni-directional rfid tag Directional antennas, like the name suggests, have a concentrated beam in one direction. Whether the beamwidth is 25 degrees or 75 degrees, directional antennas focus their gain into a specific direction to pick up tag reads. Omni-directional antennas provide a wide range of coverage in one plane. First of all, you need the keys for the tag you want to read. Due to some weaknesses in .

Monza 4 RFID tag chips possess a unique, patent-pending architecture that .Directional antennas, like the name suggests, have a concentrated beam in one direction. Whether the beamwidth is 25 degrees or 75 degrees, directional antennas focus their gain into a specific direction to pick up tag reads. Omni-directional antennas provide a wide range of coverage in one plane. SAG unveils a new omni-directional UHF RFID tag designed to provide exceptional orientation insensitivity, avoiding blind spots typical of passive single-dipole UHF RFID inlays. .. Monza 4 RFID tag chips possess a unique, patent-pending architecture that provides two fully independent antenna ports—enabling high performance, true omni-directional RFID tags for the first time. This is called True3D TM.
Both omni-directional and directional antennas are commonly sold on the RFID market. In an application where tagged items will be passing the antenna on different sides, or even near the back, an omni-directional antenna would be the best choice.
The RFID tag using the proposed antenna has exhibited a very good omni-directional reading pattern, which has shown great potential for item-level RFID applications in restaurants or libraries for tracking the items such as plates and books. 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.
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.
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.
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. The presented . 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.
