Abstract:
1. An antenna module comprising: an installation body; and a plurality of chip antennas located on said installation body, each of said plurality of chip antennas having a different resonant frequency, wherein a terminal section of each of said plurality of chip antennas is connected to a common current feeder line such that a common current signal from a feeding source is receivable by said plurality of chip antennas through the common current feeder line, said plurality of chip antennas are connected in parallel, and end parts of said plurality of chip antennas opposite to said terminal sections of said plurality of chip antennas are isolated from each other, at least two of said plurality of chip antennas forms a first antenna group of a first transmission-reception frequency band, said at least two chip antennas having different resonance frequencies that are close to each other, and at least two of said plurality of chip antennas that are different from said at least two chip antennas of the first antenna group forms a second antenna group of a second transmission-reception frequency band that is different from the first transmission-reception frequency band, said at least two different chip antennas having different resonance frequencies that are close to each other.
