A document No.2764, describing the c.a.d, of printed circuit boards has been issued by the Royal Radar Establishment, Malvern. The authors, D. A. H. Brown and A. H. James, first used Lee's algorithm for routeing. Advantages of this method are that if a path exists through the maze, the algorithm wil

A lumped element model for a double-side printed meander-line inductor with closed-form expressions for the electrical model parameters L, C, R l , and R c is presented. These structures are cheaper than coils and need less area per unit of inductance than single-side printed meander-line inductors.
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
