Abstract
A stacked patch antenna includes a circuit board, a first patch antenna, a second patch antenna, and a parasitic element. The first patch antenna is stacked on the circuit board, has a first power feeding line and a first radiation element, and receives signals in a first frequency band. The second patch antenna is stacked on the first patch antennahas a second power feeding line longer than the first power feeding line and penetrating the first radiation element to be connected to a second power feeding portion and a second radiation element smaller in size than the first radiation element, and receives signals in a second frequency band higher than the first frequency band. The parasitic element is a plate-like element disposed above the second patch antenna so as to improve elevation angle reception characteristics of the second patch antenna.
