Abstract
The prospect of a joint Millimeter Array development effort between the U.S. and Europe has led to various antenna designs. This paper describes a new 12-m antenna design that has many new features which are not widely used among existing millimeter wavelength antennas. These include: light-weight machined aluminum panels; feedlegs with triangular roofing for reflecting scattered rays to the sky; double-layered carbon- fiber reinforced plastic (CFRP) trusses on large radius supports; rotating counterweight for reducing the moment of inertia; a yoke incorporating CFRP trusses and a steel beam structure; and a displacement-measuring metrology system. A design incorporating these features could achieve a combination of high performance and reasonable overall cost. The paper also discusses in detail a number of key issues of interest for future millimeter wavelength antenna development. The design is influenced by the large number of antennas required for the Millimeter Array.
