Good morning everyone
I have a problem designing a circular loop type antenna. I have thought about making a sandwich of different dielectric /conductor layers and draw a circumference in each dielectric layer (conductor above dielectric) until the total length of the wire matches the frequency of interest (868MHz, 10 layers with a circumference of 6mm radius for each one).
These are my questions:
Can I treat my antenna as a "Circular microstrip ring" type? And if so, which dielectric should I choose a high permittivity one (er) or another with low one?
Which geometry is more interesting for this antenna, one with circumferences of the same radius or a kind of cone (spiral volume)?
Thank you for your time.
