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.

Multi-band 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.

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.

Wide-band antenna

A multi-band antenna has a strip-shaped first radiating portion disposed levelly. An end of a long side of the first radiating portion is extended downwardly to form a first grounding portion. A strip-shaped second radiating portion is disposed in alignment with and spaced from the first radiating portion. A long side of the second radiating portion is extended downwards to form a feeding portion at an end thereof away from the first radiating portion. A third radiating portion, which is stretched levelly and oppositely from an end of the second radiating portion adjacent to the feeding portion, is longer than the second radiating portion and has a long side extended downwardly to form a fixing portion adjacent to a free end thereof. The feeding portion and the fixing portion are located at the same side as the first grounding portion with respect to the first, second and third radiating portion.

A multi-band antenna has a grounding plate with a first end and a second end defined at a longer side thereof. The longer side has an upward first connecting portion adjacent to the first end and a vertical second connecting portion. A feeding portion extends downwards from a lower edge of the second connecting portion. A first antenna radiator extends towards a same direction with respect to the second connecting portion along the grounding plate from an upper side of the second connecting portion. A second antenna radiator includes a first radiating portion, a second radiating portion and a third radiating portion. A third antenna radiator extends parallel to the first radiating portion from a side of the feeding portion. A coupling component includes a first section, a second section and a third section extending opposite to the first section from an end of the second section.

Antenna

A dual-band antenna has a feeding conductor with a feeding point and a connecting portion extending downwardly from the feeding conductor. A first radiating conductor and a loop protrusion respectively extend outward from two opposite sides of the connecting portion. A grounding portion faces the loop protrusion and is spaced apart from the feeding conductor to form a small gap therebetween. A loop connection is disposed away from the feeding conductor and connects an upper portion of the loop protrusion and an upper portion of the grounding portion.
