Introduction

This book presents the design requirements of antenna integration for modern commercial devices such as smartphones, dongles, and access points. Practical use-case scenarios of smartphone and the design process of the antenna system for the same are highlighted. The feasibility of scaling up sub-6GHz to mmWave antennas is also discussed in detail followed by a plethora of design examples which could be panel mounted to modern-day commercial smartphones.

Gain Switchability

The unique requirement of gain switchability is introduced with feasible practical antenna designs.

High Efficiency Antennas for 5G

High efficiency antennas for 5G base stations is introduced along with a design example on planar all-metallic antenna.

Beam Switchability

Beam switchability requirement for base station is illustrated with a couple of compact antenna system examples.

Feeding Techniques and Future Designs

Variety of feeding techniques for mmWave antennas is elaborated in this book. Finally, low-cost antenna designs for future wireless devices are illustrated.
