Abstract:
A collective antenna device includes: a case having a gradually rising part in which spatial height increases continuously toward a rear part; a ground plate that is accommodated at a bottom part of the case; a first antenna element that is accommodated in the case and configured for a first frequency; and a second antenna element that is accommodated in the case and configured for a second frequency higher than the first frequency. The second element is accommodated in the case such that the second antenna element is located below or behind the gradually rising part and also located behind the first antenna element. A feed point of the second antenna element is located above the ground plate.
