- the reader's activation signal and responds by emitting radio waves 114.
- the reader 108 decodes the data encoded in the tag's integrated circuit and the data is passed to a host computer for processing.
- RFTD tags 106 come in a wide variety of shapes and sizes. RFTD tags 106 are categorized as either active or passive. Active RFTD tags 106 are powered by an internal battery and are typically read/write, i.e., tag data can be rewritten and/or modified. An active tag's memory size varies according to application requirements; some systems operate with up to 1MB of memory. In a typical read/write RFTD system 100, a tag 106 can provide a set of instructions, and the tag 106 can receive information. This encoded data then becomes part of the history of the tagged product 116. The battery-supplied power of an active tag generally gives it a longer read range. The trade off is greater size, greater cost, and a limited operational life.
- Passive RFID tags 106 operate without a separate external power source and obtain operating power generated from the reader 104. Passive tags 106 are consequently much lighter than active tags 106, less expensive, and offer a virtually unlimited operational lifetime. The trade off is that passive tags 106 have shorter read ranges than active tags and require a higher-powered reader.

- Core 710 may be filled with air, foam, or dielectric
- Paper has a dielectric loss factor of about 15 with a real permittivity of about 2.0. Considerable loss is created by the dielectric loss of paper. Additional loss is incurred by boundary impedance mismatches, Brewster angles, and the angle of incidence of the wave signal into the paper from the reader. Mismatch of Impedances at the boundaries:
- Fig. 8 illustrates that, depending on the angle of incidence into the core from the reader, a certain portion of the wave signal will be reflected. Assuming a TE (transverse electric) field wave, a certain portion of the incident wave will be transverse magnetically. Snell's law is used to calculate the angle of the reflected wave. The relationship between the dielectric is sufficient for calculating the reflection and transmission coefficients. A thorougl analysis matching boundary conditions to modes, to internally generated modes would produce the desired information or a geometrical optics approach may be used.
- TE transverse electric
- Each reflected wave accounts for 0.5 dB powe loss, which amounts to a loss of about 10% of the power at each boundary.
- the power loss a the paper to air boundary at the paper's core varies according to which side the antenna is disposed on compared to the angle of incidence. On the same side as the incident wave, there is no loss due to impedance mismatches. On the opposite side there is about 0.5 dB loss each way, receiving and transmitting.
