In one scenario, a pillbox array is provided. The pillbox array includes a feed network unit that receives an input wave. The feed network unit includes feed branches for splitting and transmitting the input wave, pillbox reflectors that collimate the input wave, and radiating waveguides for radiating the collimated input wave. The pillbox array further includes a load plate mounted on the feed network unit, where the load plate has load elements placed between the radiating waveguides. This pillbox array also includes a polarizer plate that is mounted on the load plate and the feed network unit. The polarizer plate includes polarizers arranged such that when the polarizer plate is laterally shifted to a first side of the radiating waveguides, a first circular polarization occurs, and when the polarizer plate is laterally shifted to a second side of the radiating waveguides, a second circular polarization occurs.

Scalable antenna array

A slicing block includes two threaded recesses, each of which intersects with a perpendicular passageway sized to require a multi-strand electric cable. A resilient saddle is guided vertically within each threaded recess by virtue of diametrically opposed vertical keyways formed through the threads of the threaded recess. A pressure screw is threadably received within each threaded recess and, when threaded into the threaded recess, engages a rear face of a saddle to reciprocate the saddle into the recess while being guided by the vertical keyways until the saddle bears upon an electric cable to clamp the electric cable into place within the perpendicular passageway.

Splicing block for multi-strand electric cable

A multiple band antenna feed used with parabolic reflector antennas and the like. The feed is arranged as two coaxially disposed waveguides. A planar array of patch elements is disposed at the end of the coaxial waveguides so the energy in each band radiates from a common phase center. This simplifies the arrangement of associated subreflectors.
