FIG. 21 - Spherical Antenna Array and Waveguide System Diagram #3039869 (License: Personal Use)

This patent-style figure depicts a radio-frequency system comprising a geodesic spherical antenna array labeled 'A', mounted atop a cylindrical base, interfaced via cable 22 to a personal computer (PC) for signal processing or control. To the right, component 'B' represents a rectangular waveguide or horn antenna with an internal Y-shaped taper and a small triangular reflector element, likely for beam shaping or impedance matching. The layout suggests a compact integrated transmitter/receiver setup used in radar, satellite comms, or 5G/6G base station prototypes.

Commonly used in technical documentation, patent filings, or engineering whitepapers to illustrate antenna-system integration; targets engineers, researchers, and product designers seeking hardware architecture details for wireless communication systems.
