The LHA-30-WR42 from Anteral is a Conical Lens Horn Antenna that operates in the K-Band from 18 to 26.5 GHz. This antenna features a plano-convex Teflon (PTFE) lens in its aperture to apply phase correction and achieve a high signal gain with low-side lobes. It provides a gain of 31 dBi and a VSWR of 1.25:1. The antenna has a 3 dB beamwidth of 4.2° in E-plane and 5.6° in H-plane. It is available in a housing that measures 226.6 mm (L) x 190 mm (Dia.) and has a WR-42 waveguide interface. The antenna is ideal for meteorological systems, communication links, testing and measurement, and radar applications.
The LHA-30-WR42 has an option with double-convex lenses to exhibit very well-defined focusing beams with short focal distances achievable in a compact size for testing and characterization purposes.
