For low Q antennas e.g. for the MicroReader, we use lacquered transformer wire.
Figure 18. Transformer Wire
The increased resistance of this wire enables us to create low Q antennas.
4.4 Antenna
Size
It has already been mentioned that, in electrically noisy situations, large antennas can
have less reading range than smaller ones
Figure 19. Reading Range Reduction due to Noise
From Figure 19, we can see how in low noise conditions, the largest antenna (RI-ANT-
G04E) has the greater range but as the noise increases, has the shortest reading
distance.
