Snaps to Connect Coaxial and Microstrip Lines in Wearable Systems

Table 4

Observed variation in S-parameters around the mean value when one connection is repeated or multiple connections are fabricated and measured. Data for 𝑆₁₁ and 𝑆₂₂:750 to 2500 MHz. Data for 𝑆₂₁:0 to 2500 MHz. The last row indicates changes in the frequency, where either one of the return losses crosses 10 dB.

	Repeated connection; (straight)	repeated connection; (bent)	fabrication
𝑆11	±0.5 dB	±0.8 dB	±1.5 dB
𝑆22	±0.6 dB	±0.7 dB	N/A
𝑆21	±0.2 dB	±0.3 dB	±0.2 dB
𝑓10 dB	±80 MHz	±120 MHz	±200 MHz
