Abstract

The invention provides a double-frequency-band microstrip antenna based on metal heterogeneous rasterization and belongs to the antenna technology field. The microstrip antenna comprises a medium plate, a microstrip paster, a grounding plate and a feed line. The microstrip paster is pasted on the upper surface of the medium plate. The grounding plate is pasted on the lower surface of the medium plate. The feed line is connected in the middle of the horizontal edge of the microstrip paster, and is pasted on the upper surface of the medium plate. The microstrip paster comprises a series of parallel horizontal metal lines and a series of parallel vertical metal lines. The arrangement modes of the horizontal metal lines and the vertical metal lines are uniform arrangement and non-uniform arrangement, or non-uniform arrangement and uniform arrangement, or both non-uniform arrangement. The double-frequency-band microstrip antenna with the structure has a double-frequency-band function, and is simple in structure, the section is small, and the frequency rate can reach 5.5 to 6, and the double-frequency-band microstrip antenna has a technical advantage of high frequency rate.

Description

technical field [0001] The invention discloses a dual-band microstrip antenna based on non-uniform metal grids and belongs to the technical field of antennas. Background technique [0002] Microstrip antennas are widely used in mobile communication and other fields due to their advantages of small size, light weight, and conformability to carriers. In recent years, with the advancement of modern airborne communications and spaceborne radars, as well as the development of smart electronic products and personal mobile communications, there is an increasing demand for low-profile, dual-band microstrip antennas. Therefore, the study of dual-band microstrip antenna has very important theoretical significance and practical application value. [0003] It is known from published articles and patents at home and abroad that gridded metal structures can be used to make microstrip patches for microstrip antennas. In the article "Meshed Patch Antennas" in "IEEE Transactions on Antenna...
