Antenna Element and Array Antenna

The invention provides an antenna element including: a radiation sheet with a first surface and a second surface arranged opposite to the first surface, and a plurality of hollowed parts penetrating through the first surface and the second surface; a plurality of feeder branches each having one end connected with a side wall of the corresponding hollow part and another end extending from the first surface far away from the first surface. Wherein the radiation sheet and the feeder branches are integrally formed by stamping, so that the antenna element provided by the invention is simple in manufacturing and the cost can be effectively reduced. Moreover, the stamped and formed antenna element can have the advantages of a smaller thickness and light weight, and large-scale array forming is facilitated.
