Using Ideal Transformer. A simple and accurate circuit model for the slotted ground plane with microstrip line has been presented by Caloz et al.
An equivalent circuit model for antenna also has been presented using ideal transformer [33].
An equivalent circuit model was presented using an ideal transformer. Both single cell and double cell structures were proposed as shown in Figure 16.
The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself.
If we want to select the ideal transformer then the windings resistance must be zero for the ideal transformer.
Figure 7 shows a case where an ideal transformer is used in an NFA.
The calculations were performed using MDS, and the magnitude or phase angle of each S parameter was varied by [+ or -]5 percent over its theoretical value for an ideal transformer. Since the magnitude of S parameters is between 0 and 1, the variation of [+ or -]5 percent translates into [+ or -]0.05 near its theoretical values.
Ideal transformers without parasitics are impossible to obtain at RF.
The CPW-to-slotline junction is simply modeled as an ideal transformer. No attempt is made to model junction parasitics.
The version of Super Compact used for this analysis (Version 1.81) does not allow this term to be evaluated directly, but it can be used with the aid of an added ideal transformer, as shown in the circuit of Figure 4.
Remember that port 2 for this calculation is across the ideal transformer, not across the device drain source terminals.
