Claims30
An antenna structure used in a folding portable radio terminal, comprising:
- a first antenna;
- and
- a second antenna,
- wherein said first antenna is used at least when said portable radio terminal is not folded, and
- said second antenna is used at least when said portable radio terminal is folded.
An antenna structure used in a folding portable radio terminal, comprising:
- a first housing part that incorporates a speaker therein;
- a second housing part that incorporates a microphone therein;
- a first antenna;
- and
- a second antenna,
- wherein said first housing part and said second housing part are capable of being folded on each other,
- said first antenna includes an antenna element and a bottom board for said antenna element,
- said antenna element is disposed in said first housing part,
- said bottom board is disposed over said first housing part and second housing part,
- for a low frequency band, said first antenna is used at least when said first housing part and said second housing part are not folded on each other,
- for said low frequency band, said second antenna is used at least when said first housing part and said second housing part are folded on each other,
- for a high frequency band, said first antenna is used at least when said first housing part and said second housing part are folded on each other, and
- for said high frequency band, said second antenna is used at least when said first housing part and said second housing part are not folded on each other.
A method of using an antenna structure used in a folding portable radio terminal, the antenna structure comprising:
- a first antenna;
- and
- a second antenna,
- wherein said first antenna is used at least when said portable radio terminal is not folded, and
- said second antenna is used at least when said portable radio terminal is folded.
A method of using an antenna structure, the antenna structure comprising:
- a first housing part that incorporates a speaker therein;
- a second housing part that incorporates a microphone therein;
- a first antenna;
- and
- a second antenna,
- said first housing part and said second housing part being capable of being folded on each other,
- said first antenna including an antenna element and a bottom board,
- said antenna element being disposed in said first housing part, and
- said bottom board being disposed over said first housing part and second housing part,
- wherein for a low frequency band, said first antenna is used at least when said first housing part and said second housing part are not folded on each other,
- for said low frequency band, said second antenna is used at least when said first housing part and said second housing part are folded on each other,
- for a high frequency band, said first antenna is used at least when said first housing part and said second housing part are folded on each other, and
- for said high frequency band, said second antenna is used at least when said first housing part and said second housing part are not folded on each other.
