A multi-band antenna includes a substrate and a conductive layer. The conductive layer covered on a top surface of the substrate includes a ground element, a first radiating element and a second radiating element. The ground element is connected with a bottom side edge of the substrate. The first radiating element is connected with one end of a lower top edge of the ground element. The first radiating element includes a connection portion, a first coupling portion, a first radiating portion and a first inductance portion. The second radiating element is connected with the other end of the lower top edge of the ground element. The second radiating element includes a second inductance portion, a second coupling portion, a second radiating portion and a third radiating portion.

Multi-band antenna

A multi-band antenna includes a base plate of which a feeding portion, a connection section and a ground portion are connected with rear, front and left edges of the base plate respectively, a first radiating element connected with a right edge of the base plate and coplanar with the base plate, a second radiating element coplanar with the base plate and the connection section and connected with an upper portion of a left rim of the connection section with a free end thereof adjacent to the ground portion, and a third radiating element connected with a lower end of the left rim of the connection section. Wherein the second radiating element is apart located between the ground portion and the third radiating element.

A multi-band antenna includes a base portion, a substantially lying U-shaped first radiating portion, a substantially lying L-shaped second radiating portion and a third radiating portion. A rear edge of the base portion extends rearward to form a ground portion with a ground point being defined thereon. A top of the base portion defines a feeding point. The first radiating portion of which one end is connected with a first side edge of the base portion and the mouth faces to the first side edge of the base portion. The second radiating portion is connected with a second side edge of the base portion. The third radiating portion tortuously extends downward from a front edge of the base portion, then extends transversely, and further circuitously extends rearward to be located substantially near under a free arm of the second radiating portion.

A multi-band antenna is disclosed and comprises a substrate and an electro-conductive layer. The electro-conductive layer comprises: a feed-in terminal; a ground terminal; a connecting portion extended forward from the feed-in terminal; a first high frequency portion extended leftward from the connecting portion for controlling a third frequency band; a low frequency portion bent and extended leftward from the connecting portion for controlling a first frequency band and a second frequency band; and a second high frequency portion extended rightward from the connecting portion for controlling a fourth frequency band. Furthermore, the second high frequency portion is connected with the ground terminal and wider than the first high frequency portion; and harmonic oscillations are generated between the second and first high frequency portions to control a fifth frequency band. Hence, the multi-band antenna of the present invention can meet the requirement of various communication standards.

Provided is a multiband printed antenna for receiving and emitting multiple electromagnetic wave signals of different bands. The multiband printed antenna includes a substrate and a conductive layer formed on a positive surface of the substrate. The conductive layer includes a grounding portion, a plurality of radiating portions controlling different bands and a single feeder point used to transmit electromagnetic wave signals. The multiband printed antenna of the present invention can separately control multiple radiating portions, which have different bands and are together formed on one same substrate, to emit the electromagnetic wave signals at one same feeder point, thereby realizing the object of the single printed antenna controlling multiple bands and greatly reducing the manufacture cost to satisfy the demand of 4G communication industry.

Multiband printed antenna

A multi-band antenna mounted on a circuit board includes a ground plate perpendicularly connected to one side edge of the circuit board, a radiating plate perpendicularly connected to the other side edge of the circuit board, and a planar antenna element includes a high frequency radiating portion, a lower frequency radiating portion, a base plate, a capacitance portion and an inductance portion. The high frequency radiating portion and the lower frequency radiating portion are located at two ends of the circuit board, respectively, and both connected to the radiating plate. The base plate is connected to the radiating plate and located between the high and lower frequency radiating portions. The capacitance portion is parallel with the ground plate to form a capacitive coupling therebetween. The inductance portion is soldered to the ground plate. A simulation inductance is formed by the inductance portion.

Antenna

A wireless mouse includes a mouse housing, a printed circuit board assembly assembled in the mouse housing, and an antenna mounted on a front end of the printed circuit board assembly. The front end of the printed circuit board assembly defines two fastening holes spaced from each other along a direction perpendicular to a front-to-rear direction. The antenna has a substantial long-strip radiating portion. Two opposite ends of the radiating portion are bent rearward and then downward to form a hook portion and a feed portion which are respectively hooked in the corresponding fastening holes to make the radiating portion transversely mounted over the front end of the printed circuit board assembly. The feed portion is electrically connected with a feed circuit of the printed circuit board assembly.

Wireless mouse

A wide-band antenna mounted on a circuit board includes a ground plate, a radiating plate perpendicularly connected to two side edges of the circuit board, and a planar antenna element which includes a base plate, an extending plate, and a ground portion. One side of the base plate defines a gap with a first coupling portion being formed, and a slot adjacent to the gap with a first strip being formed therebetween. A second strip is extended perpendicularly from the first strip. The extending plate is extended outward from one end of the base plate. The ground portion is extended outward from the second strip and connected to the ground plate. The first coupling portion and the ground portion have an interspace to form a capacitive coupling therebetween. A groove is formed among the first and second strips and the ground portion to form a simulation inductance thereamong.
