Embodiment

[0038] In this embodiment, a PCB board is used as the dielectric substrate, and then SMA connectors are soldered on. The dielectric substrate 1 is in the shape of a cube with a length of 0.8 mm, a width of 0.8 mm, and a height of 0.1 mm. The material of the dielectric substrate 1 is silicon with a relative permittivity of 11.9. The material of the radiation patch 2 is copper, the radius of the circular patch 3 is 0.16mm, the widest point of the radiation patch 2 (perpendicular to the direction of the microstrip transmission line) is 0.745mm, and the longest point (parallel to the direction of the microstrip transmission line) direction) is 0.56mm.

[0039] There are two fan-shaped rectangular grooves located on the same patch wing 2, namely the first rectangular groove 601 and the second rectangular groove 602, both of which have a width of 0.02 mm. The radius of the semicircular groove 5 is 0.04mm, and the two fan-shaped rectangular grooves on the same patch wing 2 are locat...

Abstract

The invention discloses a symmetrical multi-slot terahertz 6G communication application frequency band antenna, and belongs to the field of terahertz antennas. The symmetrical multi-slot terahertz 6Gcommunication application frequency band antenna is characterized in that the main body part of the antenna is an insulating dielectric layer; a butterfly-like radiation patch and a circular patch combined with the butterfly-like radiation patch are arranged in the center of the upper surface of the dielectric layer; the butterfly-like radiation patch and the circular patch are used for feeding together; the circular patch is combined in the radiation patch, so that ultra-wideband effect is achieved; and semicircular grooves are symmetrically formed in the left end and the right end of the radiation patch towards the farthest end of the center of the radiation patch, two sets of four rectangular grooves with the same width are formed in the left end and the right end of the radiation patchtowards the center of the radiation patch, and finally a long vertical rectangular groove is formed in the central symmetry position of the butterfly-shaped radiation patch. According to the invention, the antenna can achieve an ultra-wideband effect, the designed frequency band is located to meet the terahertz frequency requirement, ultra-wideband work can be achieved, and the antenna can be widely applied to the terahertz 6G communication frequency band, and has the advantages of being simple in structure, reasonable in design, small in size and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of terahertz antennas, in particular to a symmetrical multi-slot terahertz 6G communication application frequency band antenna. Background technique [0002] Terahertz (THz) waves in a terahertz antenna generally refer to electromagnetic waves with a frequency of 0.1-10 THz. Terahertz is a new radiation source with many unique advantages. Its energy is very small and will not cause damage to matter, so it has more advantages than X-ray technology. In addition, the vibrational and rotational resonance frequencies of many biological macromolecules are also in the terahertz band. Therefore, the development of terahertz wave technology will be beneficial to technologies in many fields such as broadband communication, radar detection, electronic countermeasures, electromagnetic weapons, astronomy, marker-free genetic inspection, cell imaging, nondestructive testing, biochemical inspection, grain selection, and strain opti...
