Abstract: 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.

Abstract: A dual-polarized antenna includes a grounding plate, a vertically polarized portion and a horizontally polarized portion. The vertically polarized portion has a first connecting portion extending from one edge of the grounding plate, a vertical radiating element spaced at the edge for forming a simulation capacitance therebetween, and a first feeding portion connected to the first connecting portion and the vertical radiating element. The horizontally polarized portion has a second connecting portion extending from another edge of the grounding plate substantially perpendicular to the edge of the grounding plate, a horizontal radiating element spaced at the another edge for forming another simulation capacitance therebetween, and a second feeding portion connected to the second connecting portion and the horizontal radiating element. The two simulation capacitances help to adjust bandwidth and input impedance of the dual-polarized antenna for improving the gain of the dual-polarized antenna.

Abstract: A wireless apparatus has a main housing, a movable housing relatively extended to the main housing. The main housing contains a first PCB with a first layer being fully laid metal material. The movable housing contains a second PCB with a second layer being fully laid metal material. An insulation route is laid on the second layer and led to the border of the second layer. A connection component electronically connects the first layer and the second layer. When the wireless apparatus is operated at wireless communication, the cooperation of the first layer, the second layer, the insulation route and the connection component adjusts the electrical characteristic of the first and second PCBs for eliminating a parasitic effect being caused of movement of the first and second PCBs and increasing gain of the antenna of the wireless apparatus.

Abstract: An embedded antenna used in mobile phone includes a lower and a higher frequency portions connecting with the lower frequency portion via a first connecting portion. The lower frequency portion is a bended structure in planar inverted F antenna (PIFA) shape. The higher frequency portion is a loop antenna working in two different higher frequencies, including a first higher frequency portion and a second higher frequency portion connecting with the first one via a second connecting portion. The first connecting portion defines a feeding portion and a grounding portion. The second higher frequency portion defines another grounding portion. An electric current is formed between the first and the second higher frequency portions and can heighten the gain and the frequency band of the antenna. Additionally, a loudspeaker is disposed in a receiving space formed between the lower and higher frequency portions to save space with lowest influence to the antenna.
