Abstract
A multi-band antenna for a printed circuit board (PCB). The PCB multi-band antenna comprises a first trace coupled to a first surface of the PCB extending along at least a portion of a length of a first side of the PCB and along at least a portion of a length of a second side of the PCB that intersects the first side, wherein the first trace is positioned proximate a perimeter of the PCB that is partially defined by the first side and the second side.
Claims22
A multi-band antenna for a printed circuit board (PCB), said multi-band antenna comprising a first trace coupled to a first surface of the PCB and extending along at least a portion of a length of a first side of the PCB and along at least a portion of a length of a second side of the PCB intersecting the first side, the first trace positioned proximate a perimeter of the PCB partially defined by the first side and the second side.
A communication device, comprising:
- a printed circuit board (PCB) having a perimeter at least partially defined by a first side, a second side, and a third side;
- and
- an antenna coupled to the PCB, the antenna comprising:
- a first trace of conductive material coupled to a first surface of the PCB, the first trace extending along at least a portion of a length of the first side proximate the perimeter and at least a portion of a length of the second side proximate the perimeter;
- and
- a second trace of conductive material coupled to a second surface of the PCB opposing the first surface, the second trace extending along at least a portion of a length of the third side proximate the perimeter and along at least a portion of the length of the second side proximate the perimeter.
A method for manufacturing a multi-band antenna coupled to a printed circuit board (PCB) having a perimeter at least partially defined by a first side, a second side, and a third side, said method comprising:
- forming a first trace of conductive material on a first surface of the PCB, the first trace extending along at least a portion of a length of the first side proximate the perimeter and at least a portion of a length of the second side proximate the perimeter;
- and
- forming a second trace of conductive material on a second surface of the PCB, the second trace extending along at least a portion of a length of the third side proximate the perimeter and at least a portion of a length of the second side proximate the perimeter.
An apparatus for mobile communication, the apparatus comprising:
- a motherboard;
- a radio having a first end and a second end;
- a first connector proximate the first end of the radio, the first connector configured to couple the radio and the motherboard;
- a coax cable having a first end coupled to the radio via the first connector, and an opposing second end;
- and
- an antenna coupled to the second end of the coax cable.
A two sided antenna, comprising:
- a dielectric substrate having a first surface and a second surface;
- a first radiator positioned on the first surface and configured to radiate a first frequency band;
- and
- a second radiator positioned on the second surface to overlap the first radiator and configured to radiate a second frequency band,
- wherein the overlap allows a weak coupling to occur between the first radiator and the second radiator, and to combine with the dielectric material and a band to split a resonate mode.
