Tag Designs and Techniques Used in HF RFID Item Level Tracking

Ronald A. Marino
No Comments
The choice and placement of a RFID tag on a product requires an investigation to determine optimal performance. The current technology of HF tags is focused on the mass production of low cost paper thin tags that have maximized read range performance perpendicular to the broad plane of the tag. Incorporating both these tag designs for use within the RFID architecture allows for flexibility of product placement and orientation while maintaining optimum performance.

Accurate and Efficient Modeling of Meander-line Polarizers

The use of PMM version 4.0 software to model the parallel and perpendicular polarization susceptance of a polarizer
Ronald A. Marino
No Comments
Accurate and Efficient Modeling of Meander-line Polarizers A meander-line polarizer is a passive broadband device used to convert the polarization properties of a wave. When designed properly, the polarizer permits a linear polarized antenna to propagate circular polarization without any significant variations in the pattern performance. Modeling of the...
