Antenna design essentials for SIGFOX Ready™ devices

June 20, 2016

Technical White paperNobody should consider antenna design as a simple afterthought when designing a SIGFOX Ready™ wireless connected device. This publication will help you to understand the key points about antennas to help you make the right choice at the very beginning of the design phase. It provides you with an understanding of the most important concepts to enable you to choose the best options for your device. Thus, it will help you understand what is important to reach "best in class" radiated performance for your SIGFOX Ready™ device.
