Abstract
There is described a patch antenna with a meandering strip feed. The antenna comprises a patch spaced from a ground plane, with the patch being substantially parallel with said ground plane, and a feed probe located between the patch and the ground plane. The feed probe comprises at least two portions parallel to the patch but spaced by different distances from the patch.
Claims17
A patch antenna comprising a patch spaced from a ground plane, said patch being substantially parallel with said ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises
- at least two portions in the space between said patch and said ground plane, parallel to said patch and spaced by different distances from the patch.
An antenna including a patch spaced from and substantially parallel with a ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises 2n portions that are parallel to said patch and spaced by different distances from the patch, and 2n+1 portions that are normal to said patch.
An antenna including a patch spaced from and substantially parallel with a ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises at least two portions parallel to said patch, and a first of said at least two parallel portions is spaced from the patch by a first distance, and a second of said at least two parallel portions is spaced from said ground plane by said first distance.
An antenna including a patch spaced from and substantially parallel with a ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises an odd number of portions parallel to said patch, and wherein at least one parallel portion is equal distance from the patch and the ground plane, and wherein all other parallel portions are disposed in pairs of equal length and with one parallel portion of each pair being disposed by a first distance from the ground plane and the other parallel portion of each pair being disposed by the same distance from said ground plane.
An antenna including a patch spaced from and substantially parallel with a ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises a conductive track formed on a printed circuit board and having at least two portions parallel to said patch and spaced by different distances from the patch.
An antenna including a patch spaced from and substantially parallel with a ground plane, and a feed probe located between said patch and said ground plane, wherein said feed probe comprises at least two portions parallel to said patch, and said feed probe is coupled to said patch directly by a normal portion that extends to and contacts said patch.
