Antenna structure for increasing isolation

Provided is an antenna structure for increasing isolation, including a ground surface, a first antenna, a second antenna, and a printed-type guiding structure; the first antenna, the second antenna, and the printed-type guiding structure are electrically connected to the ground surface; and the printed-type guiding structure is located between the first antenna and the second antenna and includes a first hollow portion, a second hollow portion, and a protruding portion. The hollow portions are parallelograms, and the angle between the axes of the hollow portions is 30°-50°. The first ends of the hollow portions overlap, and the protruding portion is disposed between the external of the first side of the first hollow portion and the interior of the first side of the second hollow portion. The second hollow portion has a short arm on the first side and a long arm on the second side. The total length of the short arm and the long arm is 0.2-0.3 times the operating frequency wavelength.
