Figure 11. User interface screen of the planar rectangular coil inductance calculator

Examples:

The following antenna parameters have to be fed to the software to compute the antenna

coil inductance:

●

the number of turns

●

the number of segments

●

w: the conductor width in millimeters

●

s: the conductor spacing in millimeters

●

the conductor thickness in micrometers

●

Length in millimeters

●

Width in millimeters

The number of turns is incremented each time a segment is added to a complete turn.
