reduction of conductive yarn content in patch antennas

What is it about?

As many conductive yarns are costly, using them to produce a patch antenna that is completely covered by conductive yarn makes them too expensive for production. Allowing a mesh to let the patch currents flow as normally as possible can yield a good quality antenna with much reduced yarn content.

Why is it important?

This has a couple of effects. Costs are reduced by reducing yarn content and production time. The antenna becomes lighter and more flexible.
