ABSTRACT:
A monopole antenna and a plurality of linear antennas each having its own predetermined electrical length are connected with a plate antenna, which is connected with a grounding plate via a single feeding point thereof, in such a way that they are connected in series to the feeding point, thereby, each of the feeding points of the antennas is united in one single point; consequently, an antenna device having broad band characteristics and multiple resonance characteristics is obtained.
