A recently granted patent (Publication Number: US11876322B2) discloses a satellite ground station antenna design that includes a hub with a circular waveguide and front-side feed network with slots and ports. The antenna features window/seals with specific dimensions and materials to ensure optimal performance. The design also incorporates a wave spring to maintain alignment between the ports, enhancing the antenna's functionality.

Furthermore, the patent details various aspects of the window/seals, including dimensions for t1, t2, and t3, which are crucial for the antenna's operation at a specific frequency. The window/seals are constructed with a dimensionally stable, low-loss dielectric material suitable for outdoor use, such as cross-linked polystyrene plastic. Additionally, the design of the window/seals helps in providing an impedance transition region and tuning frequencies to avoid interference with the operating frequency range of the waveguide circuit. When the cap engages with the pins, a radial waveguide is formed, terminated in a conductive seal and choke grooves, further enhancing the antenna's performance.
