Mi-Wave’s 257 Series spot focus antennas consist of a circular scalar feed horn illuminating a piano-convex lens. Housed in either aluminum or plastic, these horn lens antennas provide a high-efficiency beam with equal E and H plane amplitude patterns.
The 257 Series antennas are available from 8.2 to 110 GHz standard sizes of 3, 6, 9, and 12-inch lens apertures. Other custom sizes and configurations are available for our spot focus antennas, please consult Mi-Wave for further information.
