摘要:
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.

A multi-band antenna has a first radiating conductor defining a first side connected to a feeding conductor and a short portion, and a second side opposite to the first side and connected to a second radiating conductor, a third radiating conductor and a fourth radiating conductor. The second radiating conductor is arranged between the third radiating conductor and the fourth radiating conductor. The length of the first radiating conductor and the second radiating conductor resonates at a first frequency range and a second frequency range which is double frequency higher than the first frequency range. The length of the first radiating conductor and the third radiating conductor resonates at a third frequency range which is higher than and close to the second frequency range. The dimension of the fourth radiating conductor has an effect on antenna characteristics in the third frequency range.

A dual-band antenna has a first meandering portion, a second meandering portion and a connection portion defining two ends. The first meandering portion and the second meandering portion have different length. One end of the first meandering portion connects one end of the second meandering portion. The other end of the first meandering portion connects one end of the connection portion. The other end of the second meandering portion connects a feeding portion. The other end of the connection portion connects a ground portion. The feeding portion, the second meandering portion, the first meandering portion and the connection portion obtain an electrical resonance corresponding to a first frequency range. The second meandering portion obtains an electrical resonance corresponding to a second frequency range.

摘要:
A multi-band antenna adapted to a portable electrical device capable of operating in various wireless communication bands includes a first radiating conductor having opposite elongated sides, a second radiating conductor extending from one end of the first radiating conductor, a third radiating conductor arranging about a central area of the first radiating. Both the second radiating conductor and the third radiating conductor extend from the same elongated side of the first radiating conductor. A feeding body is curved and extended from the third radiating conductor. According to a position that the feeding body connecting to the third radiating conductor and designed the feeding body, operation of the multi-band antenna has a preferred range of a low frequency bandwidth and a high frequency harmonic bandwidth.

The present invention discloses a multi-band antenna, the multi-band antenna has an antenna base, a power feed portion and a grounding point. The antenna base includes a first rectangular portion, a second rectangular portion and a third rectangular portion. A first connection portion connects the first rectangular portion with the second rectangular portion, a second connection portion connects the first extending portion with the second extending portion. The power feed portion is arranged below the antenna base, and the power feed portion connects to the first rectangular portion and the second rectangular portion. The grounding point is arranged below the first rectangular portion and near the power feed portion. The first and second connection portions control the size of the electric current through the antenna base. By the above-mention unique design, the multi-band antenna can receive and transmit the signals of the different frequency bands and has a smaller volume.

摘要:
A loop-slot antenna defined by a conductive plate includes a first slot and a second slot. The first slot and the second slot divide the conductive plate into a first strip, a second strip and a patch element. The first slot is an L-shaped slot and includes a transverse slot section extending along the lower edge of the conductive plate and a longitudinal slot section extending along the left edge of the conductive plate and opening to the upper edge of the conductive plate. The first slot is operated at a first frequency. The first strip includes a transverse branch and a longitudinal branch that has a feed point. The second slot opens upward. The second strip has a free end on which a grounding point is disposed. The patch element is formed between the first and the second slots and operable at a second frequency.
