Abstract

A multiband antenna includes a feed portion, a radiating portion, and a ground via. The feed portion includes a first feed section and a second feed section paralleled to each other. The radiating portion includes a first radiator, a second radiator and a third radiator. The first radiator is L shaped with a free end. The second radiator is L shaped with a free end. The free ends of the second radiator and the first radiator extend toward to each other and partially overlap to define a slot therebetween. The third radiator includes a trapezoid section and a connecting section. The short portion includes a first short section and a second short section. The first short section connects the first radiator to the ground via, and the second short section connects the second radiator and the third radiator to the ground via.

Dependent claims

A multiband antenna, comprising:

a feed portion operable to feed electromagnetic signals and comprising a first feed section and a second feed section parallel to the first feed section;
a radiating portion connected to the feed portion, to transceive electromagnetic signals, comprising:
a first radiator being L shaped, comprising one end connected to the first feed section, and the other end being a free end;
a second radiator being L shaped, comprising one end connected to the second feed section, and the other end being a free end, wherein the free ends of the second radiator and the first radiator extend toward to each other so that the second radiator and the first radiator partially overlap, and define a slot therebetween;
and
a third radiator comprising a trapezoid section and a connecting section, wherein the connecting section connects the trapezoid section to the second feed section;
and
a short portion connecting the radiating portion to a ground via, the short portion comprising:
a first short section connecting the first radiator to the ground via, and
a second short section connecting the second radiator and the third radiator to the ground via.
