Antenna

An antenna comprising:

• a first substrate extending in a first plane direction;
• a first conductor, a second conductor, a third conductor, and a fourth conductor that are disposed on one surface of the first substrate and extend in the first plane direction;
• a coupling conductor disposed on another surface of the first substrate, the coupling conductor extending in the first plane direction, the coupling conductor capacitively coupling the first conductor, the second conductor, the third conductor, and the fourth conductor;
• a second substrate comprising a ground conductor and a power supply point, the second substrate being separated from the first substrate in a first direction, the second substrate comprising one surface facing the other surface of the first substrate, the second substrate extending in the first plane direction;
• a first pin member configured to electromagnetically connect to the first conductor;
• a second pin member configured to electromagnetically connect to the second conductor;
• a third pin member configured to electromagnetically connect to the third conductor;
• a fourth pin member configured to electromagnetically connect to the fourth conductor;
• and
• a balun disposed on one surface of the second substrate to be electromagnetically connected to the power supply point.
