PROBLEM TO BE SOLVED: To provide an integrated antenna device that includes a patch antenna and another antenna, permits downsizing, and achieves high gain of the patch antenna.SOLUTION: An integrated antenna device includes: a first antenna 10 including a tabular patch antenna element 12 and a ground pattern 11 disposed opposite to the patch antenna element 12; a second antenna 20 having a usable frequency different from that of the first antenna 10 and having, on the same plane with the ground pattern 11, a feed receiving element 21 and a parasitic element 22 disposed outside the ground pattern 11; and a filter 16 that establishes a connection between the ground pattern 11 and the feed receiving element 21 and the parasitic element 22, and becomes a low impedance at the usable frequency of the first antenna 10.SELECTED DRAWING: Figure 1 |
