Abstract
(EN)
A PC (1) includes a plurality of radio modules (10a, 10b, 10c, ...) having different frequency bands, an antenna (7) common to these, and a dielectric (8) movably arranged on one side of the antenna (7). By adjusting the interval between the antenna (7) and the dielectric (8) for each of the radio modules (10a, 10b, 10c, ...), it is possible to switch the resonance frequency of the antenna (7).

L'invention concerne un ordinateur personnel (1) qui comporte plusieurs modules radio (10a, 10b, 10c, ...) ayant différentes bandes de fréquence, une antenne (7) qui leur est commune, et un diélectrique (8) monté mobile sur un côté de l'antenne (7). En réglant l'intervalle entre l'antenne (7) et le diélectrique (8) pour chaque module radio (10a, 10b, 10c, ...), on peut commuter la fréquence de résonance de l'antenne (7).
