So, I have a helix antenna designed for 400 to 900 MHz. This antenna is designed using fabric and as a fabric, it gets wavy and scrambled which changes the performance of the helix. I am thinking of sewing a stabilizer (a thick fabric), which embroiders use so that the fabric can be stabilized as much as possible. But, I need suggestions on this idea as I do not know if I am making antenna LOSSY after sewing a stabilizer behind the fabric. I am attaching the stabilizer picture
Please advise.
Obviously the fabric has to be conductive. Your stabilizer should be insulating. The stabilizer shall provide the structural strenght only. Out of curiosity: What does your design look like?
The stabilizer would generally be a thin piece of dielectric material, so while it might have a small impact, I wouldn't expect the change to be drastic. The benefit from the added rigidity/stability would likely outweigh any deleterious effects, especially given the thought of wearing any of this in proximity of the human body, which will have a MUCH larger impact. If anything, the stabilizer helps there as well by increasing the minimum gap between the antenna and the body.
