Patent ID: 8405405

Claim:
An electro-magnetic signal sampling assembly comprising an electric field sensor and a magnetic field sensor, said sensors being incorporated in a low loss parallel plate airline (slabline); said slabline comprises an input (test) port and an output (idle) port and a center conductor connecting both ports; said electric field sensor being made as an extension (probe) of the center conductor of a coaxial cable and said magnetic field sensor being a grounded loop made using the extension of the center conductor of a coaxial cable; said electric and magnetic sensors being mounted orthogonally to each other and to the center conductor of said slabline and at the same electrical distance from the test port of said slabline, said electric field probe being inserted in the sidewall of said slabline at the approximate height of the center conductor and said magnetic field sensor being inserted perpendicularly either through the bottom or top plate of said slabline.
