ANTENNA ARRAY WITH PARTIALLY REFLECTIVE DEPOLARIZING METASURFACE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240204418 titled 'ANTENNA ARRAY WITH PARTIALLY REFLECTIVE DEPOLARIZING METASURFACE
The patent application relates to a wide scan angle antenna array in the field of radio engineering.
- The technical result of the innovation includes expanding the scanning range, increasing the efficiency of the antenna array, and reducing losses.
- The antenna array consists of multiple antenna array elements and a metasurface positioned above it.
- The metasurface is a dielectric layer with conductive elements on one side to reflect radiation from the antenna array.
- The distance between the antenna array and the metasurface is based on an integer number of half wavelengths and the operating wavelength of the antenna array.
- The predetermined scanning angle of the antenna array is also taken into account in the design.
Potential Applications: - Satellite communication systems - Radar systems - Wireless communication networks
Problems Solved: - Limited scanning range of traditional antenna arrays - Inefficiency and losses in antenna arrays
Benefits: - Expanded scanning range - Increased efficiency - Reduced losses
Commercial Applications: Title: "Advanced Wide Scan Angle Antenna Arrays for Enhanced Communication Systems" This technology can be used in satellite communication systems, radar systems, and wireless communication networks, improving their performance and range.
Questions about the technology: 1. How does the metasurface contribute to expanding the scanning range of the antenna array?
The metasurface reflects radiation from the antenna array, allowing for a wider scan angle and increased efficiency.
2. What are the key advantages of using an antenna array with a metasurface compared to traditional antenna arrays?
The main advantages include a larger scanning range, higher efficiency, and reduced losses.
Original Abstract Submitted
the disclosure relates to radio engineering, and more specifically, to a wide scan angle antenna array. technical result consists in expanding the scanning range, increasing the efficiency of the antenna array and reducing losses. antenna array is provided. the antenna array includes a plurality of antenna array elements, and a metasurface disposed above the antenna array, wherein the metasurface is a dielectric layer having, on a first side thereof, conductive elements configured to reflect part of radiation of the antenna array; the distance between the antenna array and the metasurface is based on an integer number of half wavelengths, an operating wavelength of the antenna array in a medium in the space between the antenna array and the metasurface, and a predetermined scanning angle of the antenna array.
