Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and in the embodiment of the present invention, as shown in fig. 1 and fig. 2, a dual-band combined antenna includes a metal surface (1), a first combined antenna (2), a second combined antenna (3), a first fixing clip (4), a second fixing clip (8), a first radio frequency line (5), and a second radio frequency line (9). The metal surface (1) is a regular plane, and the first combined antenna (2) and the second combined antenna (3) are positioned in the same plane and form an angle of 90 degrees with the metal surface (1). The second combined antenna (3) is positioned above the first combined antenna (2) and is formed by stamping the metal surface (1). The first fixing clamp (4) is located on the front face of the first combined antenna (2), and the second fixing clamp (8) is located on the back face of the first combined antenna.
Furthermore, a first radio frequency wire (5) penetrates through the first fixing clamp (4) to be connected with the first combined antenna (2); and a second radio frequency wire (9) passes through the second fixing clamp (8) and is connected with the second combined antenna (3).
Furthermore, the second combined antenna (3) is positioned above the first combined antenna (2) and is connected through a second feeding balun (7).
Furthermore, the first combined antenna (2) and the second combined antenna (3) are an integral body, and are connected with the metal surface (1) through the first feeding balun (6) and are 90 degrees.
Furthermore, the connection point of the two feeding baluns (7) and the first combined antenna (2) is separated by a quarter wavelength.
According to the working principle, the dual-frequency combined antenna is formed by combining two dipole antennas up and down, and the first combined antenna and the second combined antenna are both provided with feed baluns for feed balance. And the second feed balun connects the first combined antenna and the second combined antenna together, the first combined antenna becoming a reflector for the second combined antenna, the second combined antenna becoming a director for the first combined antenna. Meanwhile, the two feed radio-frequency lines penetrate through the corresponding fixing clamps and are parallel to each other, so that the mutual interference of the two groups of antennas is reduced.
In conclusion; this dual-frenquency combination antenna through put two kinds of antennas together perpendicularly, makes antenna body and plane of reflection form a whole through stamping process, and the antenna installation of being convenient for, the upper and lower antenna is each other parasitic antenna simultaneously, has expanded the bandwidth of antenna and has provided directional gain. The double-balun structure ensures the balanced feed and anti-interference capability of the antenna.
