Radio frequency performance and strain testing of an iron-on fabric shielded stripline

A shielded stripline structure made from commercially available fabric and fleece has been produced using iron-on fabrication techniques and its radio frequency performance evaluated over the range of 10 MHz to 7 GHz. Presented are the simulated and measured return loss and forward transmission characteristics. Also investigated are attachment techniques by which SMA connectors are bonded to the flexible shielded stripline. Four bonding techniques; three solder and one epoxy were evaluated by being subjected to precise mechanical loading. Copper laden solder provided the best bond strength.
