Profile: Rantec Microwave Systems, Inc. specializes in offering antennas. Our antennas are used in military & commercial applications such as radar, missile guidance, navigation, satellite communications and space. Our AK-10044 slotted array is an antenna designed for operation at millimeter wavelengths. The antenna features moderately low peak sidelobe levels, and very low RMS sidelobe levels. The four-quadrant input configuration permits single- or dual-plane monopulse operation when interfaced with the appropriate comparator. The mechanical structure consists of precision machined aluminum component parts that are dip brazed into a rugged, lightweight assembly. We have developed a line of spiral antennas specifically designed for radar warning and surveillance systems. These circularly polarized antennas can be produced singly or in phase/gain matched sets, depending on customer specifications. All antennas in the product line are designed to meet the environmental requirements of MIL-E-5400. BIT couplers are available as an option. Dual polarized spiral antennas are also available.
