Abstract
A low-profile composite antenna device includes a base plate, a first antenna, and a second antenna. The first antenna has a patch electrode capable of receiving signals in a first frequency band. The second antenna, which is capable of receiving signals in a second frequency band, has a top load part as a capacitive element. The top load part is disposed near the patch electrode of the first antenna such that it does not cover the patch electrode in a top view and that the patch electrode is located on the longitudinal extension axis of the top load part. The second antenna has at least one stub that electrically divides the longitudinal direction of the top load part into front and rear sections so as to function as a waveguide for the first antenna.
