A dual-band antenna constructed of textile material is evaluated for use in a body-worn application.  The design and evaluation are taken from a published journal paper [1].  The base antenna design is a rectangular patch constructed of a textile material covered in a conducting tape.  The patch has shorting walls and a tuning via to enhance performance and provide dual-band results.  The antenna is flexible, so it is simulated in both flat and bent conditions to gauge the impact on performance.  Radiation of the antenna over a body phantom is performed to confirm the Specific Absorption Rate (SAR) values are acceptable.  For use in MIMO applications, the patch is paired in arrays of varying configurations and evaluated.
