Modeling of integrated inductors with a coplanar ground plane using the PEEC method

Today, an exhaustive library of models describing the electrical behavior of integrated passive components in the radio-frequency range is essential for the simulation and optimization of complex circuits. In this work, a physical model for planar spiral inductors is introduced, based on a circular PEEC method. A mutual inductance formula is derived to include a coplanar ground plane and extend the model to inductors with an incomplete outer turn. The numerical solution is also discussed, including an efficient inversion procedure.

Resonant frequency, bandwidth and gain of meander line antenna

Many meander line antennas were measured for various geometry in order to realize an analysis based on experimental plan. This paper describes a method for modeling the resonant frequency, bandwidth and gain of the meander line antenna versus geometrical parameters of this antenna. It is shown that the geometrical parameters of the meander line antenna can be determined from the specified resonant frequency, bandwidth and gain. For example, many meander line antennas (MLA) have been manufactured for WLAN applications.
