HELICAL ARRAY PLANE ANTENNA

摘要

a body 1 forming a boundary of a rectangle; a plurality of T type partition 2 for including an emitting waveguide 3 and an opening side 4 between intervals in parallel at regular intervals in the body 1, and forming a sudden change waveguide 5 encompassed at a right angle to the circumference a helical wire antenna 6 for having mutually the regular interval on an upper side of each emitting waveguide 3 forming multiple antennas; a pillar 7 formed respectively at front of the opening side 4 inside of the sudden change waveguide 5; and a Low Noise Block(LNB:8) formed at the last sudden change segment of the sudden change waveguide 5.
