Antenna for small-sized radio equipment

Abstract

Abstract PURPOSE:To attain miniaturization and thin profile of a machine and also to improve the performance of maintenance by providing a conductive thin layer along a machine housing inner wall so as to form an antenna and providing a connecting means connecting the antenna and a circuit mounted on a printed board. CONSTITUTION:A press-formed thin metallic plate connected at its top and separated at its bottom is used for the antenna 4 in this invention and pins 5, 5 are implanted to the separated part at the bottom. The antenna 4 constituted in this way is inserted and fixed along the inner wall of the machine housing 6. It is simplest to use an adhesives or the like as a fixing means. A small-sized radio equipment is constituted by inserting the printed board 1 mounted with a radio equipment circuit and fixed to an operating section 7 into the machine housing 6 assembled in this way and sockets 8, 8 are provided at an opposite side to the fixed end of the operating section 7 of the printed board 1 in this case so that said sockets 8, 8 are engaged with said pins 5, 5. Said sockets 8, 8 are connected to required parts of the circuits on the printed board 1 respectively and the circuits and the antenna 4 are connected by the engagement of both.
