Electrical addressing method for a metamaterial rf antenna
A recently granted patent (Publication Number: US11757197B2) describes an innovative antenna design that utilizes a matrix drive circuitry to address and drive a plurality of radio-frequency (RF) radiating antenna elements. The antenna consists of multiple rings, with each ring corresponding to a row in the matrix. The matrix drive circuitry employs a non-grid-based addressing structure, where the majority of rows are connected to a different number of antenna elements compared to the majority of columns.
In one embodiment, all rows and columns are included in the majority, ensuring comprehensive coverage. The number of rings in the plurality of rings is equal to the number of rows, while the number of columns is determined by the sum of the elements in the innermost ring and twice the result of subtracting one from the number of rings. This configuration allows for a flexible and efficient addressing system.
Additionally, the patent mentions the use of metamaterial RF radiating antenna elements. Metamaterials are engineered materials with unique properties not found in nature, offering enhanced performance and capabilities for antennas.
The patent includes several variations of the antenna design, with different combinations of row and column lengths. However, in all cases, each row is longer than each column, which may have implications for the antenna's performance and radiation pattern.
Overall, this granted patent presents a novel antenna design that utilizes matrix drive circuitry and a non-grid-based addressing structure to efficiently drive a plurality of RF radiating antenna elements. The inclusion of metamaterial RF radiating elements further enhances the antenna's capabilities. The various embodiments provide flexibility in terms of row and column lengths, allowing for customization based on specific requirements.
