This newly expanded second edition features the latest antenna design technologies for mobile communications devices, as well as a handy step-by-step design guide for simple engineers. Readers will get a practical understanding of how the techniques available can be balanced against device restrictions. Other highlights include MIMO antenna design, measurements, and requirements, advanced matching techniques, and a thorough discussion of internal and external antennas including device-specific examples. Thoroughly updated, the book concludes with the latest regulations and compliance techniques for Specific Absorption Rate (SAR) and Hearing Aid Compatibility (HAC).
