Antenna with expansion compensation structures for thermal expansion
A recently granted patent (Publication Number: US11909091B2) discloses an innovative antenna design featuring an array of antenna elements coupled to a structure with multiple components made of materials with varying coefficients of thermal expansion (CTEs). The structure includes components pin bonded together, allowing for movement between components due to thermal expansion. The design ensures that the materials with higher CTEs are used for the first and second components, while the other components have lower CTEs, enabling controlled movement for optimal performance.
Furthermore, the patented antenna design incorporates pins made of materials that do not impact radio-frequency (RF) propagation, such as dielectric pins or polystyrene material. The structure also includes slots that facilitate movement between components in response to thermal expansion, ensuring stability and efficiency. Additionally, the antenna feed within the structure utilizes bonded composite dielectric materials, including sintered and corrugated dielectric materials, enhancing the overall performance of the antenna elements in radiating RF energy. The array of antenna elements themselves are capable of radiating RF energy and are specifically designed as RF radiating metamaterial antenna elements of a metasurface, showcasing advanced technology in the field of antenna design.
