HORIZONTALLY POLARIZED OMNI-DIRECTIONAL ANTENNA APPARATUS AND METHOD |
| 摘要 |
An Alford antenna array having at least three driven elements disposed on a substrate, a first portion of each driven element being disposed on one side of the substrate, and a second portion of said each driven element being disposed on a second side of the substrate. At least one of the driven elements has a bent-dipole Alford loop coupled to two feed points and has an acute-angle dipole feed point and acute-angle loaded ends. In other embodiments, the driven elements may comprise any combination of bent-dipoles and/or folded-and-bent dipoles. In further embodiments, six dipoles are concentrically disposed about a central point, where three of the dipoles may operate at a different frequency than the other three dipoles. |
