Angle is+45 degree or -45 degree.(referring to Fig. 4)
It should be noted that dual-band and dual-polarization ceramics label also can single polarization two-frequency operation.This mode of operation also provides
Two reading distance peak values, and the two peak values occur simultaneously.
In other words, without using the reader antenna of different polarization modes.Specifically,
A) reader antenna can be linear polarization or circular polarisation.
If b) using Linear polarization reader antenna, then the putting position of label is it is required that its center line and linear polarization
Angle between the main polarization direction of reader antenna is 0 degree or 90 degree.
If c) using recognition circular polarization reader antenna, then to the alignment angle between reader antenna and label without spy
It is different to require.
Two reading distance peak values are located near the centre frequency of the super high frequency radio frequency identification frequency range in country variant or area.
For example, embodiment illustrated in fig. 4 provides two reading distance peak values in Europe and US bands respectively.In two readings
Between the frequency range where peak value, reading distance significantly shortens, and is misread so as to reduce.The frequency of two reading distance peak values
Even their priority can be adjusted neatly.
It is a kind of embodiment that can be selected of dual-band and dual-polarization ceramics label below：
