Dual-arm modified-spiral textile antenna for wearable medical communication applications

This paper provides a dual-arm modified-spiral magnetic-type textile antenna for wireless medical communication applications. The proposed antenna is constructed of a woven fabric substrate and a copper patch on the substrate aiming at 2.45 GHz band operation. The antenna is simulated and measured with and without human body phantom. The antenna shows magnetic characteristics by comparing the power field density between E- and H-field at near field region. Moreover, the measurement shows that the antenna is well suited with the simulation results, especially the reflection coefficient parameter.
