Abstract

In this publication is described a multifrequency antenna (200) for personal radio transceiver which comprising a groundplane (201), a planar conductive layer (204) which acting as a resonator plane, at least one connecting point (210) which connecting galvanically resonator plane (204) to groundplane (201) and matching bridge (212). Main purpose of invention is add one resonant frequency to EGSM-band. Apparatus of the invention comprising a planar conductive surface (205) and first resonator (214.1) which extending from side area of planar surface (205) and second resonator (214.2) which is above planar surface (205).
