    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.

    摘要: 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.

    摘要: 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 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.
