Abstract
To facilitate the constitution and operativity of a helical antenna included in a communication terminal equipment such as a portable telephone. An antenna device includes a circuit board 10 on which a communication circuit is arranged, a shield case 20 arranged on this circuit board and shielding at least a part of an interior of the circuit with a conductor film formed on a part of an outer surface or an inner surface, a conductor pattern 23 formed into a predetermined pattern on a portion 22 of the surface or the inner surface of the shield case on which portion the conductor film is not formed, and a feeder section 12 for making the conductor pattern continuous with an antenna connection section of a communication circuit arranged on the circuit board.
Claims3
An antenna equipment comprising:
- a circuit board;
- a housing arranged on said circuit board;
- an antenna conductor pattern formed into a predetermined pattern on one of an outer surface of said housing and an inner surface of said housing;
- and
- a feeder section for making a circuit and being formed on said circuit board and being an extension of said antenna conductor pattern, wherein
- said housing is formed of a resin having an electrical conductor film arranged on a portion other than a neighborhood of a portion thereof on which said antenna conductor pattern is arranged;
- and
- said electrical conductor film is brought into contact with a ground potential section of said circuit board to thereby function as a shield.
A communication terminal equipment comprising:
- a circuit board on which a communication circuit is arranged;
- a shield case arranged on said circuit board and shielding at least a part of an interior of said circuit with a conductor film formed on one of a part of an outer surface of the shield case and an inner surface of the shield case;
- a conductor pattern formed into a predetermined pattern on one of a portion of the outer surface and the inner surface of said shield case on which portion the conductor film is not formed;
- and
- a feeder section making said conductor pattern continuous with an antenna connection section of the communication circuit arranged on said circuit board.
