ABSTRACT:
The conducting path width of a spiral printed circuit coil is reduced for the inside of the spiral coil to obtain more inductance in the same space without substantial sacrifice in Q. In another form of spiral coil with non-constant path width, the path width is reduced in a sector of the coil located between the inner and outer terminals to reduce the distance between terminals with minimum sacrifice in inductance or Q.
