10 Ω and 20 Ω. In case that the resistance of the antenna is less than 5 Ω or more than 30 Ω, the output driver of the ID RW24 is working off-specification, which may lead to a drastical reduction of the reading range. FEIG ELECTRONIC GmbH Seite 5 von 15 h80391-1e-ID.doc... -

(see also figure 3.1-2). Please notice that the relation of edge length a and b does not ex- ceed a value of 2:1. In order to reach a maximum reading range, the number of turns with the highest inductance has to be choosen.

70 cm and the gate width should not exceed 1m. The inductance of a gate antenna in Anti-Helmholtz arrangement is slightly smaller than the sum of all inductances of the two single antennas. FEIG ELECTRONIC GmbH Seite 12 von 15 h80391-1e-ID.doc... -
Page 13: Gate Antenna In Mixed Arrangement
In the object identification sector , this arrangement is however advantageous for systems with lower gate widths, since here the identification probability increases compared to the other two arrangements. FEIG ELECTRONIC GmbH Seite 13 von 15 h80391-1e-ID.doc... -
