Connection strategies for wearable microwave transmission lines and antennas

In this paper a range of connection strategies are investigated for application to flexible passive microwave devices. The binding theme of all solutions is a simple manufacturing process and compatibility with textile materials. Three potential connection strategies are presented - snap-on buttons, butterfly clasps and wing solution. All the connection strategies are evaluated on a perpendicularly fed microstrip line. Based on the electrical performance, manufacturing complexity and mechanical stability, the best connection strategy is suggested for microwave applications in practical on-body environments.
