An array antenna comprising:
- a first antenna element and a second antenna element configured to transmit and receive radio waves;
- and
- a feeding line configured to feed the first antenna element and the second antenna element in series, wherein
- the first antenna element and the second antenna element respectively have a feeding element fed from the feeding line and a parasitic element part having a parasitic element, the parasitic element part being provided to face the feeding element, and
- a number of the parasitic element of the parasitic element part in the first antenna element is different from a number of the parasitic element of the parasitic element part in the second antenna element.
An antenna element comprising:
- a feeding element as a slot;
- and
- a plurality of parasitic elements provided to face the feeding element, wherein
- the plurality of parasitic elements include at least a pair of the parasitic elements, the pair of parasitic elements being separately provided with a H-plane in a center of the feeding element as a border and being excited in-phase in a basic mode.
