ABSTRACT:
Antenna structure 10 has a primary reflective surface 12 over which is positioned a subreflector surface 14. Support webs 32, 34 and 36 are made of low dielectric loss insulating material and are adhesively secured in slots in the reflectors. The support webs are positioned on planes through the axis so that the small thickness of the webs is in the projected area and results in an unobstructed and undistorted electromagnetic radiation pattern. The webs firmly support the subreflector in the desired position. The antenna can be configured as a Gregorian system as shown or alternatively as a Cassegrainian system.
