why do rfid tags have dual dipole atenna This article presents a damped double dipole antenna design enabling UHF RFID tags that are able to sense changes in resistance of a sensing element (with a conductivity similar to that of . You could clone the card on to a small sticker (the size of a quarter) that you could stick on to the back of your phone. It'd be the same effect (put your phone against the reader and it let's you in) and it will work when your phone's dead. 2. Reply. Award. I want to use my phone as a NFC .

Some dual-band RFID (radio frequency identification) tag antennas were obtained from symmetric dipole type configurations by exploiting the harmonic frequencies.Some tags, such as the Symbol 'X' tag shown below (the big black on the right), have two orthogonal antennas, allowing them to respond to any polarization vector in the plane of the tag; these are often known as dual dipole tags.This article presents a damped double dipole antenna design enabling UHF RFID tags that are able to sense changes in resistance of a sensing element (with a conductivity similar to that of .Two antennas provide polarization diversity for reading an RFID tag that a single antenna is not able to read due to the tag orientation. Many of the above issues associated with conventional patch antennas are overcome by the specially .
In many RFID practical applications, it is required that reader can effectively read tags which are placed in radiation covering area randomly. In this paper, a passive UHF dual-dipole tag .Two prototype devices have been designed and fabricated: a mono-band folded dipole UHF-RFID tag, and a dual-band UHF-RFID tag based on a spiral resonator coupled to a folded dipole . Some dual-band RFID (radio frequency identification) tag antennas were obtained from symmetric dipole type configurations by exploiting the harmonic frequencies. Based on . In this paper, a passive UHF dual-dipole tag antenna with quasi-isotropic patterns is designed, which can reduce the sensibility of tag read-orientation in a long distance.

This paper analyzes the slotted microstrip antenna equivalent circuit and the slot theory, and then describes a novel slot-coupled dual-band dipole antenna for RFID tag. The basic purpose of creating dual dipole UHF RFID tags is to provide tags with the capability of omnidirectional receiving and transmitting of RF waves. In some ways, dual dipole tags are similar to circularly polarized RFID antennas in an RFID system because they allow for reading RFID-tagged items regardless of tag orientation.
