A multiband printed antenna includes a circuit board, a radiator unit and a grounding unit. The radiator unit is arranged on the circuit board. The radiator unit includes a feed-in portion, a first radiant portion slantwise extended upward and rightward from a right of a first top edge of the feed-in portion, and a second radiant portion extended rightward and then extended upward from a first right edge of the feed-in portion. The first radiant portion is formed in a strip shape. The second radiant portion is formed in a lying L shape. A first inner edge of the second radiant portion is separated from a top end of the first radiant portion. The grounding unit is arranged on the circuit board. The radiator unit and the grounding unit are separated from each other.

Multiband printed antenna

A wireless dongle includes a circuit board, a connector disposed to a front of the circuit board, a wireless module and a printed antenna. The circuit board has a first front edge, a first rear edge, a first lateral edge, and a second lateral edge opposite to the first lateral edge. The circuit board has a first surface, and a second surface opposite to the first surface. The wireless module is disposed to a middle and one side of the first surface which is adjacent to the first lateral edge. The wireless module is disposed to a middle and one side of the second surface. The printed antenna is disposed at the other side of the first surface and the other side of the second surface which are adjacent to the second lateral edge. The wireless module is electrically connected between the connector and the printed antenna.

Wireless dongle

A multiband printed antenna includes a radiation unit and a grounding unit. The radiation unit is arranged at a right of a circuit board. The radiation unit includes a first radiation part, and a second radiation part which is extended upward and then is bent rightward from a left of a top edge of the first radiation part. The grounding unit is arranged at a left of the circuit board. The grounding unit is separated from the radiation unit. The grounding unit includes a first extension, a second extension straightly extended leftward from a top of a first left edge of the first extension, a grounding part straightly extended leftward from a bottom of the first left edge of the first extension, and a third extension straightly extended leftward from a middle of the first left edge of the first extension.

A wireless dongle includes a circuit board, a connector, a wireless module and a printed antenna. The circuit board has a first front edge, a first rear edge, a first left edge and a first right edge. The connector is disposed to a middle of a front of the circuit board. The wireless module is disposed to a middle area and a left area of the circuit board. The connector is electrically connected to the wireless module. The printed antenna is positioned at a right area of the circuit board. The printed antenna is a monopole antenna. The wireless module is connected between the connector and the printed antenna. The printed antenna has a feed-in section positioned close to the first rear edge of the circuit board, and a radiation section.

A multiband printed antenna includes a radiator arranged on an upper portion and one end of a circuit board, and a grounding body. The radiator includes a feed-in part, a first radiation part straightly extended rightward from an upper section of a first right edge of the feed-in part, and a second radiation part sequentially extended rightward, then extended upward, later extended leftward, and further extended downward from a lower section of the first right edge of the feed-in part. The grounding body is arranged on a lower portion of the circuit board. The grounding body is positioned adjacent to a lower portion of a second right edge of the radiator. The grounding body is separated from the radiator.

A wireless dongle includes a circuit board, a universal serial bus connector, a wireless module and a printed antenna. The circuit board has a front edge, a rear edge, a left edge and a right edge. The universal serial bus connector is arranged at a middle of the front edge of the circuit board. The wireless module is arranged at a left area and a middle area of the circuit board. The universal serial bus connector is electrically connected to the wireless module. The wireless module includes a radio frequency chip. The radio frequency chip is arranged on a front right area of the wireless module. The printed antenna is arranged at a right area of the circuit board. The radio frequency chip is arranged between the universal serial bus connector and the printed antenna.
