Abstract
Abstract Rows of generally parallel elongated conducting members, parallel to the polarization of an electromagnetic wave and intersecting a dielectric slab, are used to control the path of such wave. The invention may take the form of a waveguide. A waveGuide utilizes a slab of insulating material. Two parallel rows of metallic posts, with each post generally perpendicular to the slab, intersect the slab. The rows of posts are spaced apart a distance at least equal to 0.6 lambda o where lambda o is the free space wavelength for the lower end of the operational wavelength range of the circuit. The radio frequency energy transmitted down the waveguide is polarized electrically in a direction parallel to the axes of the posts. The new waveguide, in one of its forms, is ideally suited to constitute an antenna, and is so shown as one form of the invention. The new waveguide is also ideally suited to interconnect the components of an electric circuit, and therefore I have also illustrated a portion of a circuit with the electronic components interconnected by the new waveguide.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
A waveguide for electromagnetic waves comprising at least two juxtaposed dielectric materials of different dielectric constants, one of which is a slab and another of which extends away from both faces of the slab, said slab being oriented generally perpendicular to the direction of polarization of said waves, said dielectric materials taken together constituting means for carrying the electromagnetic waves as surface waves with part of said waves traveling in said slab, and wave guiding means comprising at least two rows of many elongated conducting members, each such member being embedded in said slab and extending through the slab and away from both sides of the slab and arranged generally parallel to each other member of the same row traNsverse to the slab, each row constituting reflecting means to form collectively a waveguide so that the waves traveling along the waveguide bounce back and forth between the rows, each of the conducting members in the same row being so closely spaced to each adjacent conducting member as to maintain the major energy flow between the rows, said dielectric slab extending between conducting members of the same row and beyond the rows forming the waveguide.
Claim 2
Dependent Claim
194 words
