Abstract :
A new type of "around-the-mast" rotary joint is described. This rotary joint features low insertion loss, negligible rotational variations in transmission characteristics, and low SWR over a broad band of frequencies. This device is unique in that any reasonable number of identical units can be used in combination as a microwave slip-ring system, thereby offering improved performance of multi-beam rotary antenna systems.
