I am wondering is this a rare field?

Adam Abramowicz

You may compare quartz parameters to other material parameters i.e. permittivity, losses, etc. Then you will find out the answer quite easily.

@Adam,

Permittivity for fused quartz is 3.8 and loss tangent a@3GHz is 0.00006. Should it be very good for radiation efficiency?

As you see permittivity is relatively low thus miniaturization issue fails. Losses are small enough. You should also consider price.

I see what you mean now, thanks.
