A radio communication device, comprising:
- a case;
- a circuit board mounted inside the case;
- an antenna apparatus that is fed electricity from the circuit board;
- and
- one or a plurality of antenna improving elements that are each arranged inside the case and each have a line section with one end grounded at one point to a ground of the circuit board and with another end open, wherein:
- the antenna improving element resonates at a same frequency as said antenna apparatus;
- the antenna improving element is arranged near a central portion of the case along a longitudinal direction thereof;
- and
- the antenna apparatus is arranged near an end of the case along the longitudinal direction thereof.
- wherein the antenna improving element is bent to fit inside the case along a shape of an inner surface thereof.
A radio communication device, comprising:
- a first case;
- a second case connected to the first case in a foldable fashion via connecting means;
- a circuit board mounted inside the first case;
- an antenna apparatus that is arranged inside the first case and is fed electricity from the circuit board;
- one or a plurality of antenna improving means that are each arranged inside the first case and each have one end grounded at one point to a ground of the circuit board and with another end is open, wherein:
- the antenna improving means resonates at a same frequency as said antenna apparatus;
- the antenna improving means is arranged near the connecting means;
- and
- the antenna apparatus is arranged in a position more distant from the connecting means than the antenna improving means,
- wherein the antenna improving element is bent to fit inside the first case along a shape of an inner surface thereof.
