An antenna is compactified whilst being able to operate across at least two different broad frequency bands. An antenna circuit board 7 on which an antenna pattern 7a and a passive element pattern 7b are formed is accommodated inside an antenna case. An antenna element is connected electrically to the upper end of the antenna pattern 7a. An antenna operating in the GSM and DCS frequency bands is constituted by a telephone element provided on the lower portion of the antenna element and the antenna pattern 7a and passive element pattern 7b formed on the antenna circuit board 7. Thereby, a compactified antenna is enabled to operate across two different broad frequency bands.
