Problems solved by technology

[0004] In the design process of the M-shaped slot antenna, the broadband antenna of the application frequency band is considered first, and the trend of miniaturization of wireless communication products is considered in the design concept. In the previous antenna design, most broadband antennas have a large volume, while It is undoubtedly not suitable for today's wireless communication products that require thin, light and short

Abstract

The present invention relates to the technical field of antennas and in particular to a slot antenna. A dielectric substrate is provided with a rectangular radiating plate and an M-type radiating plate. The rectangular radiating plate is provided with a parasitic coupling body and is provided with an opening. A horizontal slit and a vertical slit are formed between the parasitic coupling body andthe rectangular radiating plate. The M-type radiating plate includes a left radiating plate and a right radiating plate which are symmetrically disposed. A first slit is disposed between the left radiating plate and the right radiating plate. Second slits are disposed on both the left and right radiating plates. The slot antenna can increase the bandwidth of a 5G frequency band by providing the horizontal slit and the vertical slit between the parasitic coupling body and the rectangular radiating plate, can increase the gain of a 2G frequency band by providing the first slit and the second slits on the M-type radiating plate, so as to have a wide frequency band, a small size, simple structure and low cost. The slot antenna has high efficiency, high gain and good radiation pattern.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a slot antenna. Background technique [0002] Microstrip antennas currently on the market have the characteristics of low profile, light weight, small size, and easy fabrication. In recent years, microstrip antennas have been extensively studied and widely used in wireless communication devices. Although the microstrip antenna has so many advantages, its shortcomings such as narrow frequency band, low efficiency, poor polarization, and discrete feeding and radiation points need to be continuously improved and studied. In particular, the demand for frequency bands in wireless communication systems is getting higher and higher. [0003] The M-shaped slot antenna specifically aims at the shortcomings of the current technology and makes a breakthrough. [0004] In the design process of the M-shaped slot antenna, the broadband antenna of the application frequency band is considere...
