Embodiment 1
[0030] The concept of microstrip radiator was first proposed by Deschamps in 1953. Patented in 1955 by French Cutton and Baissinot. The first practical antennas were developed by Howell and Munson, and since then extensive research and development has been done on microstrip antennas and arrays aimed at exploiting their great advantages such as light weight, small size, low cost, conformal structure and compatibility with integrated circuits, etc., which led to various applications, and led to the broad field of microwave antennas, the subject of microstrip antennas was established as an independent entity.
[0031] This embodiment designs a chipless RFID radio frequency tag with a microstrip antenna, which consists of three microstrip units forming an antenna array. The three microstrip antenna units have different resonant frequencies, and the resonant frequencies are close to each other, all in the range of 2.1GHz- In the range of 2.5GHz, select the appropriate side le...
Embodiment 2
[0038] In order to reduce the cost of the label and expand the application range of the label, the chipless RFID radio frequency label can be simplified to a structure with only two antennas. A horizontally planned disc monopole antenna is connected to a vertically polarized dipole antenna. The polarization directions of the antennas are orthogonal, and the polarization diversity also isolates the sending and receiving signals. Frederic Croq et al. have designed a signal layer composed of multiple parallel dipole resonators of different lengths, and a microstrip antenna with aperture coupling feeding, which can achieve three resonant frequencies in the range of 4.5GHz-7.5GHz; Faton Tefiku and others have designed a dual-frequency dipole antenna. The long pair of dipoles work at 0.9GHz, and the short pair of dipoles work at 1.5GHz.
[0039] This embodiment designs a kind of chipless RFID radio frequency label of dipole antenna, and its manufacturing process is as follows: ...
