<P>PROBLEM TO BE SOLVED: To provide a multi-frequency antenna which can be embedded in a housing of radio transmitter and resonated at a plurality of frequency bands. <P>SOLUTION: Conductive antenna patterns 1a and 1b, divided into two, are formed on a mounting substrate 100 comprising a portable radio transmitter. Each one end of the patterns 1a and 1b is connected with chip component mounting lands 2a and 2b, a reactance component 4 is mounted on the mounting lands 2a and 2b. As a result of this configuration, a multi-frequency antenna which is embedded in the portable radio transmitter and resonated at a plurality of frequency bands is achieved, and the mounting substrate and the antenna of the portable transmitter can be formed in one piece. <P>COPYRIGHT: (C)2003,JPO |
