A test fixture is mounted to a supporting base and adapted for holding an electronic device, such as a laptop computer, a mobile phone and so on, on the purpose of testing an antenna characteristic of the electronic device. The test fixture includes a first fixing component and a second fixing component. The first fixing component is adapted for being mounted to the supporting base and has a first basic plate adapted for carrying the laptop computer. The second fixing component is removably mounted to the first fixing component, and has a plurality of supporting rods suspending above the first basic plate adapted for clamping the mobile phone therebetween.

Test fixture

A multi-band antenna includes a first radiating portion, a second radiating portion extending perpendicularly from the first radiating portion, a third radiating portion extending perpendicularly from the second radiating portion and located at a same side with respect to the second radiating portion as the first radiating portion, a fourth radiating portion extending perpendicularly from the third radiating portion towards the first radiating portion, a fifth radiating portion in alignment with the first radiating portion, with a feeding portion connecting with the first radiating portion and the fifth radiating portion, a sixth radiating portion extending perpendicularly towards the fourth radiating portion from the fifth radiating portion and spaced away from the fourth radiating portion, and a grounding portion spaced from the first radiating portion, the feeding portion and the fifth radiating portion with a grounding area disposed thereon, and connected with the first radiating portion by a connecting portion.

Multi-band 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.

Dual-band antenna

A portable audio wireless communication device cooperating with a portable electrical apparatus with a display component has a plug for matting with the portable electrical apparatus, a speaker and a cable connected the plug and the speaker. The plug has a signal contact connected one end of a signal wire of the cable, a ground contact connected one end of a matching antenna wire of the cable, a first antenna contact connected one end of a first antenna wire and one end of the matching antenna, and a second antenna contact connected one end of the second antenna of the cable. When the portable audio wireless communication device operates at wireless communication, cooperation of the first antenna wire and the matching antenna wire resonates at UHF broadcast band, and the second antenna wire resonates at FM broadcast band and VHF broadcast band.

Portable audio wireless communication device

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.
