Abstract :
We present an antenna modeling method based on partial element equivalent circuit (PEEC) theory. The antenna is modeled as an equivalent circuit of lumped circuit elements, which enables circuit co-simulation between the antenna and circuits in both time and frequency domains. Antenna radiation is captured as an equivalent radiation resistor. For verification, a 2.4-GHz transmitter with bondwire antenna was implemented in a standard digital 0.35μm CMOS technology. Measurement shows good agreement with the proposed model. This model can be applied to any other on-chip electromagnetic structures.
