Abstract

A portable terminal, which has easily adjustable reception sensitivity, includes an operating section side case section (2) having a first case member (30) which forms appearance; a display section side case section (3); a circuit section (33), which is arranged on the operating section side case section (2) or the display section side case section (3), and has a ground section (31), a power feed section (32), and a signal processing section (36) connected to the power feed section (32); a first conductive section (34), which is arranged on the operating section side case section (2) and electrically connected to the ground section (31); and a second conductive section (35) which is arranged on the display section side case section (3) and electrically connected to the power feed section (32). The first conductive section (34) is formed in the first case member (30).

Claims

1. A portable terminal comprising:

a dipole antenna including a grounding portion and a radiating element;

a first body including a first case member that forms an exterior;

a second body;

a circuit portion disposed in either one of the first body and the second body, and including a ground portion, electric power supply portion, and signal processing unit connected to the electric power supply portion;

a first conductive portion formed in the first case member, and electrically connected to the ground portion; and

a second conductive portion disposed in the second body, and electrically connected to the electric power supply portion;

wherein one side of the first case member is configured to be relatively movable away from the first body in a state the other side of the first case member is connected to the first body;

wherein the grounding portion of the dipole antenna is the first conductive portion formed in the first case member; and

wherein the radiating element of the dipole antenna is the second conductive portion.

2. A portable terminal according to claim 1, wherein the first case member is formed from metal.

3. A portable terminal according to claim 1, wherein the first case member is a decoration case.

4. A portable terminal comprising:

a dipole antenna including a grounding portion and a radiating element;

a first body;

a second body including a second case member forming an exterior;

a circuit portion disposed in either one of the first body and the second body, and including a ground portion, an electric power supply portion, and a signal processing unit connected to the electric power supply portion;

a first conductive portion disposed in the first body, and electrically connected to the ground portion; and

a second conductive portion formed in the second case member, and electrically connected to the electric power supply portion;
