A partial-element circuit model for meander line inductors printed on circuit boards is proposed and its relation with the physical layout is derived. A procedure for the design is presented allowing to obtain inductances between 8 and 50 nH in the range from 30 to 1000 MHz with a 5% mean error.
## Abstract This article investigates the influence of milling process on properties of printed microwave circuits. Furthermore, design guidelines are proposed for optimizing the milling process by leaving large unmilled copper surfaces on the board without deteriorating circuit performance. The pr
Several methods used for the prerouting analysis of printed circuit boards are compared. The quality of a method is expressed as the correlation between predicted at~f actual values of objective measures of (in interconnection problem complexity. The experimental data confirm that some indicators of
