View Patent ↗A wireless communication apparatus that includes a first antenna section having a first power feed point; a second antenna section having a second power feed point; a first electrically conductive plate extending between the first antenna section and the second antenna section; a second electrically conductive plate disposed substantially in parallel with the first electrically conductive plate and extending between the first antenna section and the second antenna section; and a short-circuiting member that electrically short-circuits the first electrically conductive plate and the second electrically conductive plate to each other such that a slit is formed by a part of a periphery of the first electrically conductive plate and a part of a periphery of the second electrically conductive plate.
1. A wireless communication apparatus comprising:
a first antenna section having a first power feed point;
a second antenna section having a second power feed point;
a rectangular shaped housing, wherein the first antenna section is disposed at a first lengthwise end of the housing and the second antenna section is disposed at a second lengthwise end of the housing;
a rectangular shaped ground plate extending between the first antenna section and the second antenna section;
a rectangular shaped electrically conductive plate including a printed circuit board of the wireless communication apparatus and disposed substantially in parallel with the ground plate and extending between the first antenna section and the second antenna section, wherein a surface area of the ground plate and a surface area of the conductive plate are substantially the same; and
a plurality of short-circuiting members that electrically short-circuit the ground plate and the conductive plate to each other such that a slit configured to function as at least one of a slit antenna and slot antenna and having a length substantially half a wavelength of a frequency used by the wireless communication apparatus is formed by a part of a periphery of the ground plate and a part of a periphery of the conductive plate between the plurality of short-circuiting members.
2. The wireless communication apparatus of claim 1 , wherein
the first antenna section and the second antenna section are disposed apart from one another by a predetermined distance.
3. The wireless communication apparatus of claim 1 , wherein
the slit is formed between the first antenna section and the second antenna section and extends along a periphery of a lengthwise side of the housing.
4. The wireless communication apparatus of claim 1 , wherein
the first power feed point and the second power feed point are disposed in the vicinity of the slit.
5. The wireless communication apparatus of claim 1 , wherein
the plurality of short-circuiting members are electrically conductive members.
6. The wireless communication apparatus of claim 5 , wherein
the plurality of electrically conductive members are a plurality of electrically conductive pins.
7. The wireless communication apparatus of claim 1 , wherein
the short-circuiting member comprises a second conductive plate.
8. The wireless communication apparatus of claim 1 , wherein
the ground plate includes an electrically conductive housing panel of the wireless communication apparatus.
9. The wireless communication apparatus of claim 1 , wherein
the electrically conductive plate includes a metal plate that reinforces a display panel of the wireless communication apparatus.
10. The wireless communication apparatus of claim 1 , wherein
the electrically conductive plate includes an electrically conductive housing panel of the wireless communication apparatus.
11. A wireless communication apparatus comprising:
a first antenna section having a first power feed point;
a second antenna section having a second power feed point;
a rectangular shaped housing, wherein the first antenna section is disposed at a first lengthwise end of the housing and the second antenna section is disposed at a second lengthwise end of the housing;
a rectangular shaped ground plate extending between the first antenna section and the second antenna section;
a rectangular shaped electrically conductive plate including a printed circuit board of the wireless communication apparatus and disposed substantially in parallel with the ground plate and extending between the first antenna section and the second antenna section, wherein a surface area of the ground plate and a surface area of the conductive plate are substantially the same; and
means for electrically short-circuiting the ground plate and the conductive plate to each other such that a slit configured to function as at least one of a slit antenna and slot antenna and having a length substantially half a wavelength of a frequency used by the wireless communication apparatus is formed by a part of a periphery of the ground plate and a part of a periphery of the conductive plate.
