The approach in this book is historical and practical. It covers “basic designs” in more detail than other microstrip antenna books that tend to skip important electrical properties and implementation aspects of these types of antennas. Examples include: quarter-wave patch, quarter by quarter patch, detailed design method for rectangular circularly polarized patch, the use of the TM11 (linear and broadside CP), TM21 (monopole CP pattern) and TM02 (monopole linear) circular patch modes in designs, dual-band antenna designs which allow for independent dual-band frequencies. Limits on broadband matching are discussed. The appendix contains useful simple matching approaches, design details (gain, matching, sidelobes) of the little-studied omnidirectional microstrip antenna (OMA), limits and properties of common single and dual band Planar Inverted F Antenna (PIFA) antenna designs.

The second edition has numerous additions to the earlier text which will make the concepts presented clearer. New cavity model analysis equations of circular polarization bandwidth, axial ratio bandwidth and power fraction bandwidth have been included. The section on omnidirectional microstrip antennas is expanded with further design options and analysis. This also true of the section on Planar Inverted F (PIFA) antennas. The discovery and description of the “fictious resonance” mode of a microstrip slot antenna has been added to that section. Appendix A on microstrip antenna substrates has been expanded to provide more detail on the types of substrate and their composition. This is often neglected in other texts. An appendix on elementary impedance matching techniques has been added as these methods have proven useful in my industrial work. 

Key Features

• Gives a complete introduction to useful elegant microstrip antenna designs that may be engineered unlike many other designs.

• Provides extensive section on the design of omni-directional microstrip antennas. De-mystifies basic PIFA designs and expands on their limitations. Discusses Electrically Small Antenna (ESA) limits, which are generally ignored by other books.

• Appendices provide instruction on ways to implement numerical methods for designs. The appendices also cover practical aspects of substrate materials, copper thickness, dielectric values, types of plastics (thermoset and thermoplastic) and the manufacturing process of Teflon fiberglass boards.

• Provides practical suggestions for solution of difficulties encountered in physical designs (e.g. shorting pin in center of patch for ESD, use of small strips on either side of feed pin to provide stress relief from shock and vibration).
