M.E.C.’s X390-647 (4×9-Element) is an X-band, Series-Fed patch array antenna possessing low side lobe levels and narrow beamwidth. This lightweight, low-profile antenna provides a directional beam with high efficiency and is suitable for a variety of modern satellite communications and multipurpose radar applications. This antenna can be mounted on both flat and conformal surfaces due to its low-profile and planar form factor. By varying the size of appropriate patches in subarrays, one can compensate for curvature effects in conformal mounting.
M.E.C.’s X390-638 (16-Element) and X390-645 (36-Element) are X-band, waveguide slot array antennas possessing a high power handling capability. These lightweight, low-profile antennas provide a directional beam with high efficiency and are suitable for a variety of multipurpose radar applications.
M.E.C.’s horn lens antennas consist of a Rexolite lens, fed by a corrugated conical horn in an aluminum housing. The inner surface of the lens contains surface matching grooves to reduce VSWR. The corrugated horn produces symmetrical illumination of the lens with low spillover. The resultant far-field pattern has sidelobes of approximately -25 dB and cross-polarization at -30 dB. Beam efficiency is greater than 92%. Typical VSWR is 1.3:1.
These parts are mechanically rugged and can withstand vibration, temperature extremes, wind, and rain. Any polarization and connector interface can be provided with the application of appropriate transducers. Dual frequency performance can also be obtained using a diplexer (e.g. 10.7 and 37 GHz or 6.8 and 10.7 GHz).
