Step 9: EM Optimizing the Antenna Matching Circuit
The matching of the antenna was then performed, which was a bidirectional matching from the antenna into the PA itself.
The AWR Microwave Office circuit elements can be used to parameterize the inductors/capacitors in the AWR AXIEM or
Analyst simulators. For example, MRINDNB2 can be used for a rectangle inductor and MICAP for an interdigital capacitor.
Many other models are available, and imported PDK elements can be used as well. Once the EM models were parameterized,
the antenna matching circuit could be optimized. Figure 23 shows the EM optimization for the antenna matching output
impedances (top right) of the PA.

of the layout structure with the antenna.
