Abstract
Various embodiments relate to antenna panels with different geometries. Two or more log-periodic panels, such as log-periodic antenna panels, can be arranged along about the same plane next to one another. In one example, two panels can be employed, a first panel and a second panel. These panels can have a geometry, with the first panel having a first geometry and the second panel having a second geometry that is a mirror of the first geometry.
Claims20
A system, comprising:
- a first log-periodic antenna panel with a first geometry;
- and
- a second log-periodic antenna panel with a second geometry,
- where the first log-periodic antenna panel and the second log-periodic antenna panel are arranged along about the same plane next to one another and
- where the first geometry and the second geometry are different in orientation.
2 more elements
A system, comprising:
- a first log-periodic antenna panel with a first geometry;
- a second log-periodic antenna panel with a second geometry;
- a first ground plate coupled to the first log-periodic antenna panel that causes the first log-periodic antenna panel to be more directional;
- a second ground plate coupled to the second log-periodic antenna panel that causes the second log-periodic antenna panel to be more directional;
- a first feed coupled to the first log-periodic antenna panel;
- a second feed coupled to the second log-periodic antenna panel;
- and
- a management component configured to manage the first feed to be at a normalized 0 degrees and to manage the second feed to be at a 180 degree offset from the first feed,
- where the first log-periodic antenna panel and the second log-periodic antenna panel are arranged along about the same plane next to one another and
- where the first geometry and the second geometry do not match in orientation.
