Microstrip Open End Block

Block Selection Tree: MicrostripStubsMicrostrip open end

This type of block implements the open-end effect of a microstrip line. The following figure illustrates the layout.

The reference plane is marked RP1 in the above diagram.

The block is characterized by the properties listed below. To modify the values, use the Block Properties – Parameters dialog box. The common substrate properties are defined by a Microstrip Reference Block.

The properties listed above and the substrate properties of the reference block define the electrical behaviour of the block. The layout view uses another set of layout properties. These properties define the position of the block in the layout view. The electrical behaviour of the block does not depend on these properties.

The open end adds a capacitance that effectively lengthens the microstrip line. The additional length is calculated from a formula developed by Hammerstad.
