The effect of different structures of embroidery patch antenna on polymer substrate with identical embroidery properties

This paper presents a novel class embroidery patch antenna on polymer composite - polydimethylsiloxane (PDMS). By lamination and polymer integration, different structures of fully embroidered polymer patch antenna with ground plane have been designed, fabricated and tested. Analysis of the effect of conductive patch weight, conductive characteristics using different embroidery structure on antenna performance has been carried out. The measured results show that although double embroidered layer on one side of fabric has similar conductivity and identical embroidery properties as two-sided embroidery, the antenna performs better using two-sided embroidery structure.
