Antenna

An antenna comprising:

• a base;
• a ground layer formed on the base;
• a first antenna portion comprising:
• a first main body;
• a first upright portion perpendicular to the ground layer, the first upright portion comprising a first end coupled to one end of the first main body and a second end electrically connected to the ground layer;
• and
• a second upright portion perpendicular to the ground layer, the second upright portion comprising an upper end connected to the first main body, and a lower end electrically connected to the base, a connection point between the first upright portion and the ground layer serving as a first grounded point, and a connection point between the second upright portion and the base serving as a first feeding point;
• a second antenna portion arranged between the first upright portion and the second upright portion, the second antenna portion comprising:
• a second main body;
• a third upright portion perpendicular to the ground layer, the third upright portion comprising a top end connected to one end of the second main body, and a bottom end electrically connected to the base;
• and
• a fourth upright portion perpendicular to the ground layer, the fourth upright portion comprising a topmost end connected to the second main body, and a lowermost end electrically connected to the ground layer, a connection point between the third upright portion and the base serving as a second feeding point, and a connection point between the forth upright portion and the ground layer serving as a second grounded point;
• and
• an isolation slot being formed in the ground layer between the first antenna portion and the second antenna portion.
