Fundamental Physics of Planar Inductors, Embedded Planar Transformers, and Planar (Patch) Antennas

Abstract

This chapter provides a comprehensive review of the existing information|knowledge of planar spiral inductors, embedded planar transformers, and planar (patch) antennas. The review starts with examining Maxwell's laws of electrodynamics that govern propagation of electromagnetic waves through conductors and dielectrics (insulators)—here the focus is on electromagnetic wave propagation through conductors. This key knowledge is then applied to analyze and understand the properties and performance metrics of planar spiral inductors, embedded planar transformers, and planar (patch) antennas.
