Abstract:
A waveguide switch comprising:a first transmission line having a first end and a second end; a rotary joint having a first side and a second side, said first side rotationally coupled to said second end of said first transmission line; a joint rotation device coupled to said rotary joint, whereby said joint rotation device rotates said rotary joint; a rotary transmission line having a first rotary end and a second rotary end, said first rotary end rigidly coupled to said second side of said rotary joint, whereby said rotary transmission line rotates with said rotary joint; at least two second transmission lines, each of said second transmission lines having a third end and a forth output end, said third end of one of said second transmission lines coupled to said second rotary end of said rotary transmission line through a non-contacting waveguide, said non-contacting waveguide including a waveguide gap, whereby said second rotary end of said rotary transmission line may rotate between said third ends of each of said second transmission lines; and a controller coupled to said joint rotation device, said controller having control logic operative to control said joint rotation device to rotate said rotary joint to align said rotary transmission line with one of said second transmission lines.
