Antenna structure and antenna array structure

An antenna structure comprising:

• an antenna board including a first surface and a second surface that is opposite to the first surface;
• a plurality of patch antenna elements arrayed on the first surface of the antenna board;
• a feeding electrode formed on the second surface of the antenna board and electrically connected to each of the plurality of patch antenna elements;
• a power supply control board that is disposed away from the second surface of the antenna board, extends in a direction intersecting the second surface of the antenna board, and includes a third surface and a fourth surface that is opposite to the third surface;
• and
• a connection member disposed on the second surface of the antenna board and on at least one of the third surface and the fourth surface of the power supply control board, the connection member electrically connecting the feeding electrode and the power supply control board,
• wherein the power supply control board includes a connection terminal, and
• the connection member includes
• a body having an insulation property,
• an electrode part formed on a surface of the body,
• a first joint that joins the electrode part and the feeding electrode by metal joining, and
• a second joint that joins the electrode part and the connection terminal by metal joining.
