The EH1840 from Microwave Vision Group is a Dual-Ridge Horn that operates from 18 to 40 GHz. This linearly polarized horn provides a gain of up to 19 dBi and has an antenna factor of 42 dB/m. It can handle an input power of up to 15 W and has a VSWR of less than 1.90:1. This antenna has a unique design that prevents the excitation of unwanted higher-order modes in the aperture and delivers a well-defined smooth radiation pattern throughout the operational bandwidth. This lightweight horn for EMC Testing measures 2.50 x 2 x 8.6 cm and has a 2.92 mm (female) connector. It is suitable for radiated emission testing in accordance with FCC, MIL-STD461, and SAE ARP 958 standards.
