12 .4 – 140 GHz, Prime Focus Antennas

Diameters from 18 to 72 inches


Mi-Wave’s 202,203 Series prime focus antennas consist of a parabolic reflector, a linearly-polarized primary feed, and a feed support assembly, that is attached to the rim of the reflector in order to position the feed accurately. Tapped holes are provided on each antenna for mounting. For applications that require larger diameters, the 203 Series prime focus antennas feature metalized fiberglass reflectors and cover a frequency range from 12 .4 to 140 GHz . They are available in diameters from 18 to 72 inches with low surface tolerances (typically 0 .0023 inch RMS.

Prime Focus Antennas

If you are looking for prime focus antennas, then you’ve come to the right place. At Millimeter wave products Inc. (Mi-Wave) we specialize in manufacturing the highest quality prime focus antennas for many needs. What makes our prime focus antennas the best choice?

The 202 Series antennas feature a precision aluminum reflector which provides excellent performance at millimeter wave frequencies between 18 to 140 GHz and diameters from 3 to 24 inches are available . This design is recommended for frequencies where low surface tolerances (typically 0 .001 inch RMS) are critical for electrical performance . The characteristics of the 202 Series makes them well-suited for applications where high performance is necessary.
