Opis: Reverberation Chambers (RCS) - Applications in Antennas and Electromagnetic Compatibility (EMC) Meas - Yi Huang, Stephen Boyes

This book covers important and timely issues in Reverberation Chambers (RCs) and their applications to EMC and Antenna measurements. Developed specifically for university students, researchers, practicing industrial engineers and designers who work with antennas in radio frequency (RF) engineering, EMC, radar, and radio communications. This book will provide the reader with a firm theoretical and practical understanding of the RCs operation, allowing them to undertake practical antenna and EMC measurement work with confidence and accuracy. The book is built on many years of research by the authors that encompass many of the new advances in antenna design.About the Authors viii Acknowledgements x 1 Introduction 1 1.1 Background 1 1.2 This Book 3 References 5 2 Reverberation Chamber Cavity Theory 7 2.1 Introduction 7 2.2 Cavity Modes and Electromagnetic Fields 8 2.3 Mode Stirring Techniques 17 2.4 Plane Wave Angle of Arrival 21 2.5 Average Mode Bandwidths 24 2.6 Chamber Quality (Q) Factor 26 2.7 Statistical Forms 30 2.8 Line of Sight Elements 44 2.9 Reverberation Chamber as a Radio Propagation Channel 52 References 56 3 Mechanical Stirrer Designs and Chamber Performance Evaluation 58 3.1 Introduction 58 3.2 Paddle Design Methodology 61 3.3 Numerical Analysis 63 3.4 Comments on Practical Validation 78 3.5 Measurement Parameters for Validation 80 3.6 Measurement Results 81 3.7 Summary 92 References 92 4 EMC Measurements inside Reverberation Chambers 94 4.1 Introduction to EMC 95 4.2 EMC Standards 98 4.3 EMC Measurements and Tests 101 4.4 EMC Measurements Inside Reverberation Chambers 103 4.5 Comparison of Reverberation Chamber and Other Measurement Facilities for EMC Measurements 123 4.6 Conclusions 127 Acknowledgements 127 References 127 5 Single Port Antenna Measurements 129 5.1 Introduction 130 5.2 Definitions and Proof: Antenna Efficiency 131 5.3 Definitions: Textile Antennas 134 5.4 Measurement Procedures 134 5.5 Free Space Measurement Investigation 138 5.6 On Body Antenna Measurements 145 5.7 Theoretical and Simulated Evidence 161 5.8 Measurement Uncertainty 163 5.9 Summary 166 References 167 6 Multiport and Array Antennas 169 6.1 Introduction 169 6.2 Multi port Antennas for MIMO Applications 171 6.3 Measurement Parameters 174 6.4 Diversity Gain from Cumulative Distribution Functions (CDF) 175 6.5 Diversity from Correlation 180 6.6 Channel Capacity 185 6.7 Embedded Element Efficiency 186 6.8 Definitions: Conventional Array Antenna Measurements 191 6.9 Measurement Parameters 192 6.10 Deduction of Characterisation Equation 194 6.11 Measurement Results 196 6.12 Measurement Uncertainty 200 6.13 Summary 200 References 201 7 Further Applications and Developments 203 7.1 Shielding Effectiveness Measurements 203 7.2 Antenna Radiation Efficiency Measurements without a Reference Antenna 209 7.3 Antenna Diversity Gain Measurements without a Reference Antenna 213 7.4 Wireless Device and System Evaluation 214 7.5 Other Reverberation Chambers and the Future 216 7.6 Summary 218 References 218 Appendix A: Deduction of Independent Samples 220 Appendix B: Multivariate Normality Test for SIMO Channels 225 Appendix C: Surface Current Nature 230 Appendix D: BS EN 61000 4 21 Standard Deviation Results 235 Index 240
