ABSTRACT:
The present invention provides an antenna in which a single exciting point can be commonly used by a plurality of frequencies, particularly, a small multi-mode plate antenna, and a small and cheap multi-media wireless apparatus using the antenna. In the antenna, a slit2is formed in a conductive plate1, and resonance is made at an exciting point3provided in a part of the conductive plate around the slit2. Further, enclosed openings4, 6are formed in parts which are capacitive when seen from the exciting point3on the conductive plate1, and inductances are formed by conductive strips5, 7in the enclosed openings4, 6respectively. Another resonance is generated by the conductive strips5, 7. In such a manner, resonances corresponding to a plurality of frequencies are realized at the exciting point3.
