Abstract
A patch antenna includes a first patch element and a second patch element. Each patch element defines a center. The second patch element is spaced below the first patch element. A connection point is defined on the second patch element for connection to a transmission line. A first plane is defined through the connection point and the center of the second patch element and generally perpendicular to the second patch element. The first patch element is disposed offset the second patch element such that the center of the first patch element does not intersect with the first plane.
Claims20
A patch antenna comprising:
- a first patch element having a center;
- a second patch element having a center and spaced from and non-planar with said first patch element;
- a connection point defined on said second patch element for a connection to a transmission line;
- a first plane defined through said connection point and said center of said second patch element and generally perpendicular to said second patch element;
- and
- said first patch element disposed offset said second patch element such that said center of said first patch element does not intersect with said first plane.
A patch antenna comprising:
- a first patch element having a center;
- a second patch element having a center and spaced from and non-planar with said first patch element;
- said first patch element defines a periphery having a first length and said second patch element defines a periphery having a second length different from said first length;
- a connection point defined on said second patch element for a connection to a transmission line;
- a first plane defined through said connection point and said center of said second patch element and generally perpendicular to said second patch element;
- a second plane defined through said center of said first patch element and said center of said second patch element and generally perpendicular to said patch elements;
- and
- wherein an angle between said first and second planes is about 45 degrees.
