Antenna Structure

An antenna structure, comprising:

• a dielectric substrate, comprising a first surface and a second surface;
• a first radiation sheet, arranged on the first surface, comprising a first part and a second part connected with the first part;
• a second radiation sheet, arranged on the first surface, comprising a third part and a fourth part connected with the third part, wherein a gap is between the second radiation sheet and the first radiation sheet;
• and
• a feeder, arranged on the second surface, comprising a first end for inputting an excitation signal and a second end for feeding an excitation signal to the first radiation sheet and the second radiation sheet;
• wherein the first part, the third part and the gap form a slot antenna, and the second part and the fourth part form a dipole antenna.
