Abstract

Abstract A portable radio communication apparatus includes a printed circuit board, an antenna section and a radio section installed on the board, a housing, and a connector. The radio section includes electronic parts of which connecting terminals are connected to the printed circuit board and of which conductor sections formed on outer surface thereof are connected to the grounding section. The housing accommodates therein the printed circuit board, the antenna section, and the radio section. The housing has a conductor film formed on an inner surface thereof. The conductor sections of the electronic parts are connected to the conductor film on the inner surface of the housing via the connector. Since the shielding case and the connector conventionally used are unnecessary, the size and weight of the apparatus can be reduced.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 135 words
A portable radio communication apparatus having antenna means and radio means which are shielded from an external space, comprising: a printed circuit board having a grounding section; antenna means mounted on said printed circuit board; radio means mounted on said printed circuit board, said radio means including electronic parts, each of said parts having a connecting terminal connected to said printed circuit board and having a conductive section formed on an outer surface thereof, said conductive section being connected to said grounding section; a housing for accommodating therein said printed circuit board, said antenna means, and said radio means, said housing having a conductive film on an inner surface thereof; and connecting means for connecting the conductive section of each of said electronic parts to the conductive film on the inner surface of said housing.
Claim 2
Dependent Claim 25 words
An apparatus as claimed in claim 1, wherein said antenna means is connected to said radio means via wirings disposed on said printed circuit board.
Claim 3
Dependent Claim 30 words
An apparatus as claimed in claim 1, wherein said conductive film is formed in a region of said housing other than a region thereof where said antenna means is accommodated.
Claim 4
Dependent Claim 23 words
An apparatus as claimed in claim 1, wherein said electronic parts are disposed in the vicinity of the periphery of said antenna means.
Claim 5
Dependent Claim 36 words
An apparatus as claimed in claim 1, wherein said connecting means includes metal pieces and elastic projections formed on said metal pieces, said projections connecting the conductive sections of said electronic parts to the conductive film.
