Radio frequency interconnect systems and methods

A radio frequency (RF) interconnect comprising:

• an antenna suspended air stripline (SAS) having a first and second opposing surfaces, the second surface having a first conductor and a first cavity, wherein the first cavity forms a first portion of a ridged waveguide;
• a receiver SAS having a first and second opposing surfaces, the first surface having a second conductor and a second cavity, wherein the second cavity forms a second side of the ridged waveguide;
• and
• an electromagnetic interference (EMI) gasket disposed at an interface established between the first cavity and the second cavity to electromagnetically seal a slot formed by the ridged waveguide,
• wherein energy is transmitted between the antenna SAS and the receiver SAS through the ridged waveguide.

A radio frequency (RF) interconnect comprising:

• a first substrate having first and second opposing surfaces, the first substrate having a first plurality of cavities formed in the second surface, wherein each of the plurality of cavities form respective first sides of a corresponding plurality of ridged waveguides;
• a first suspended air stripline (SAS) transmission line provided in the first substrate, with at least a portion of the first SAS transmission line extending into at least a portion of one of the first plurality of cavities;
• a second substrate having first and second opposing surfaces with the first surface of the second substrate disposed over the second surface of the first substrate, the second substrate having a second, like plurality of cavities formed in the first surface, wherein each of the second plurality of cavities form respective second sides of a plurality of ridged waveguides such that with the first surface of the second substrate disposed over the second surface of the first substrate the plurality of first and second cavities in the respective first and second substrates form a plurality of ridged waveguides;
• a second suspended air stripline (SAS) transmission line provided in the second substrate, with at least a portion of the second SAS transmission line extending into at least a portion of one of the second plurality of cavities;
• and
• an electromagnetic interference (EMI) gasket disposed at an interface between one of the first and second cavities to electromagnetically seal at least one slot formed by the plurality of ridged waveguides,
• wherein at least one of the plurality of ridged waveguides is configured to couple RF energy between the first SAS transmission line and the second SAS transmission line and wherein the first SAS transmission line and the second SAS transmission line are separated by a predetermined distance from each other.
