Abstract
Description
Claims (9)
- A multi-band antenna, comprisingat least one low-band sub-antenna; andat least one high-band sub-antenna comprising at least one high-band dipole and a reflector;wherein the high-band dipole and/or the reflector are/is structured and positioned so that current induced in the high-band sub-antenna by the low-band sub-antenna is directed to reflector over an extended effective distance in proportion to wavelength of the low-band sub-antenna.
- The multi-band antenna of claim 1, wherein the high-band dipole is spaced from the reflector, and is coupled to the reflector via a metal line.
- The multi-band antenna of claim 2, wherein the high-band dipole is spaced from the reflector by a PCB board on which the metal line is located.
- The multi-band antenna of claim 1, wherein the high-band dipole is spaced from the reflector, the high-band sub-antenna further comprises a metal bracket which is spiral-shaped and configured to couple the high-band dipole to the reflector, and the metal bracket is positioned under the high-band dipole or beside the high-band dipole.
- The multi-band antenna of claim 2, wherein the metal line is spiral-shaped and is located or embedded on an insulated portion of the high-band dipole, wherein one end of the metal line is connected to a conductive portion of the high-band dipole and another end of the metal line is connected to reflector.
- The multi-band antenna of claim 1, wherein a spiral-shaped slot is punched in the reflector around the high-band dipole.
- The multi-band antenna of claim 6, wherein the high-band sub-antenna further includes a metal box located beneath the reflector configured to cover the spiral-shaped slot to improve front to back ratio of the high-band sub-antenna.
- The multi-band antenna of any of claims 1-3, wherein the extended distance is in form of at least a cable and a metal box/block located beneath the reflector through which the high-band dipole is coupled to reflector.
- The multi-band antenna of claim 1, wherein the extended distance is in proportion to one fourth or one eighth of the wavelength of the low-band sub-antenna.
