Abstract
A radio frequency (RF) coupler for passing RF energy through a dielectric such as glass, includes first and second circuit boards, each board having disposed thereon an electrical conducting material, the first and second circuit boards being arranged opposite each other on opposing sides of the dielectric, the first circuit board having a first ground element that defines a first aperture, and a first exciter strip disposed within the first aperture, the second circuit board having a second ground element that defines a second aperture, and a second exciter strip disposed within the second aperture, wherein one of the first and second exciter strips is longer than the other.
Claims26
A through glass coupler, comprising:
- a first module comprising a first circuit board having a left side edge, a right side edge, a top edge and a bottom edge, the circuit board of the first module further having a front face and a back face, the front face having a ground element that is disposed adjacent at least one of said right side edge and said left side edge and at least one of said top edge and said bottom edge, the front face of the first circuit board further having a first module exciter strip disposed within an aperture defined at least in part by the ground element;
- and
- a second module comprising a second circuit board having a left side edge, a right side edge, a top edge and a bottom edge, the second circuit board of the second module further having a front face and a back face, the front face having a ground element that is disposed adjacent at least one of said right side edge and said left side edge and at least one of said top edge and said bottom edge, the front face of the second circuit board further having a second module exciter strip disposed within an aperture defined at least in part by the ground element,
- wherein the second module exciter strip is longer than the first module exciter strip in at least one dimension, and
- wherein the ground element of the first circuit board comprises a gap between portions of the ground element.
A radio frequency (RF) coupler for passing RF energy through a dielectric, the coupler comprising:
