Abstract
Abstract The antenna 10 comprises a line of radiating columns 12 extending transversely to the line and a plurality of conducting rods 14 interspersed among the columns 12. The conducting rods 14 are aligned along two lines 22a, 22b to form two reflecting arrays spaced one behind the other with respect to the look direction 11 of the antenna 10. The spacing is one quarter wavelength at the operating frequency.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
An antenna comprising a plurality of radiating columns and a plurality of conducting rods, said radiating columns being disposed in a line and extending transversely to said line, a first set of said conducting rods being parallel to said radiating columns and disposed in a line to form a first reflecting array, and a second set of said conducting rods being parallel to said radiating columns and disposed in a line to form a second reflecting array, said second array being spaced behind said first array relative to the look direction of the antenna.
Claim 2
Dependent Claim
94 words
An antenna comprising a plurality of radiating columns and a plurality of conducting rods, said radiating columns being disposed in a line and extending transversely to said line, a first set of said conducting rods being parallel to said radiating columns and disposed in a line to form a first reflecting array, and a second set of said conducting rods being parallel to said radiating columns and disposed in a line to form a second reflecting array, said second array being spaced behind said first array relative to the look direction of the antenna.
Claim 3
Dependent Claim
27 words
An antenna according to claim 1, in which the spacing of said first and second arrays is substantially one quarter of the operating wavelength of the antenna.
Claim 4
Dependent Claim
22 words
An antenna according to claim 1, in which said radiating columns comprise a plurality of dipole radiators supported by a supporting column.
Claim 5
Dependent Claim
21 words
An antenna according to claim 3, in which said dipole radiators are polarized transverse to the line of said radiating columns.
Claim 6
Dependent Claim
42 words

Claim 8
Dependent Claim
47 words
An antenna according to claim 3, in which said supporting column comprises a stripline connector for conveying signals to and from said dipole radiators, a substrate, and two electrically grounded, conducting planes, said stripline being mounted on said substrate which is sandwiched between said two conducting planes.
Claim 9
Dependent Claim
42 words
An antenna according to claim 4, in which said supporting column is a cylinder of electrically conducting material, and the antenna further comprises means for conveying signals to and from said dipole radiators, said signal conveying means being housed in said cylinder.
Claim 10
Dependent Claim
16 words
An antenna according to claim 8, in which said signal conveying means is a coaxial line.
Claim 11
Dependent Claim
47 words
An antenna according to claim 4, in which said supporting column comprises a stripline connector for conveying signals to and from said dipole radiators, a substrate, and two electrically grounded, conducting planes, said stripline being mounted on said substrate which is sandwiched between said two conducting planes.
