Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
56 words
A microwave directional aerial comprising at least one microstrip line having a ground plate, an insulating plate and a conductive strip superimposed upon each other, said strip having edges; means for feeding to said line ultrahigh frequency energy; both edges being laterally set off in the same direction at uniformly spaced points, thus forming radiating discontinuities.
Claim 2
Dependent Claim
56 words
A microwave directional aerial comprising at least one microstrip line having a ground plate, an insulating plate and a conductive strip superimposed upon each other, said strip having edges; means for feeding to said line ultrahigh frequency energy; both edges being laterally set off in the same direction at uniformly spaced points, thus forming radiating discontinuities.
Claim 3
Dependent Claim
62 words
A microwave directional aerial comprising a plurality of parallel, equally spaced lines having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edges; means for feeding to said lines ultrahigh frequency energy; both edges of each line being laterally set off in the same direction at uniformly spaced points, thus forming radiating discontinuities.
Claim 4
Dependent Claim
62 words
A microwave directional aerial comprising a plurality of parallel, equally spaced lines having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edges; means for feeding to said lines ultrahigh frequency energy; both edges of each line being laterally set off in the same direction at uniformly spaced points, thus forming radiating discontinuities.
Claim 5
Dependent Claim
89 words
A microwave directional aerial comprising a plurality of parallel equally spaced lines, having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edgeS; means for feeding to said lines ultrahigh frequency energy; both said edges being laterally set off in the same direction, thus forming along a predetermined length of said strips radiating discontinuities, said discontinuities being spaced apart by the length in said microstrip of the operating wave and said predetermined length being the same for all the strips.
Claim 6
Dependent Claim
89 words
A microwave directional aerial comprising a plurality of parallel equally spaced lines, having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edgeS; means for feeding to said lines ultrahigh frequency energy; both said edges being laterally set off in the same direction, thus forming along a predetermined length of said strips radiating discontinuities, said discontinuities being spaced apart by the length in said microstrip of the operating wave and said predetermined length being the same for all the strips.
Claim 7
Dependent Claim
115 words
A microwave directional aerial comprising a plurality of parallel equally spaced strip lines, having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edges; both said edges being laterally set off in the same direction thus forming along a predetermined length of said strips radiating discontinuities, said discontinuities being spaced apart by the length in said microstrip of the operating wave and said predetermined length being the same for all the strips; a wave guide extending normally to said strip lines, said guide having a pair of large walls, one of said walls supporting said ground plate; and probes respectively coupling said strips to said guide.
Claim 8
Dependent Claim
115 words
A microwave directional aerial comprising a plurality of parallel equally spaced strip lines, having a common ground plate and a common insulating plate, each line having a conductive strip, said strips having edges; both said edges being laterally set off in the same direction thus forming along a predetermined length of said strips radiating discontinuities, said discontinuities being spaced apart by the length in said microstrip of the operating wave and said predetermined length being the same for all the strips; a wave guide extending normally to said strip lines, said guide having a pair of large walls, one of said walls supporting said ground plate; and probes respectively coupling said strips to said guide.
