Claims
- 1. A mobile communication terminal comprising:
a first antenna element connected to a circuit substrate contained in a terminal cabinet, and arranged inside the terminal cabinet; and a second antenna element arranged in one of a first state included in the terminal cabinet and a second state extended from the terminal cabinet, and adapted to be electromagnetically coupled with one of ends of the first antenna element in a state extended from the terminal cabinet.
- 2. The mobile communication terminal according to claim 1, wherein the second antenna element is, in the second state, extended from the terminal cabinet in a direction parallel to the circuit substrate.
- 3. The mobile communication terminal according to claim 1, wherein both the first antenna element and the second antenna element are arranged between the circuit substrate and a rear surface of the terminal cabinet.
- 4. The mobile communication terminal according to claim 1, wherein a connection point connecting the first antenna element to the circuit substrate is separated from an electromagnetic coupling point of electromagnetically coupling the first antenna element and the second antenna element, an electromagnetic field generated at the connection point and another electromagnetic field generated at the electromagnetic coupling point being not influenced by each other.
- 5. The mobile communication terminal according to claim 1, wherein the first antenna element is formed to radiate a principal polarized wave from the first antenna element in a direction perpendicular to the extending direction of the second antenna element and the second antenna element is formed to radiate a principal polarized wave from the second antenna element in the extending direction of the second antenna element.
- 6. The mobile communication terminal according to claim 1, wherein length of the first antenna element and length of the second antenna element are different from each other, and selected based on wavelengths of respective radio waves which are transmitted and received via the first antenna element and the second antenna element.
- 7. The mobile communication terminal according to claim 1, wherein one of ends of the second antenna element is arranged between the first antenna element and the rear surface of the terminal cabinet when the second antenna element is extended.
- 8. The mobile communication terminal according to claim 1, wherein one of ends of the second antenna element is arranged between the first antenna element and the circuit substrate when the second antenna element is extended.
- 9. The mobile communication terminal according to claim 1, further comprising a magnetic material member arranged in a position opposite to the first antenna element on the circuit substrate.
- 10. The mobile communication terminal according to claim 9, wherein the magnetic material member is formed in flat plate-shaped and the first antenna element is formed in flat plate-shaped, the first antenna element formed being arranged in a position opposite to the magnetic material member formed.
- 11. The mobile communication terminal according to claim 9, wherein one of ends of the second antenna element is arranged between the first antenna element and the rear surface of the terminal cabinet when the second antenna element is extended.
- 12. The mobile communication terminal according to claim 9, wherein one of ends of the second antenna element is arranged between the first antenna element and the circuit substrate when the second antenna element is extended.
- 13. The mobile communication terminal according to claim 10, wherein one of ends of the second antenna element is arranged between the first antenna element and the rear surface of the terminal cabinet when the second antenna element is extended.
- 14. The mobile communication terminal according to claim 10, wherein one of ends of the second antenna element is arranged between the first antenna element and the circuit substrate when the second antenna element is extended.
