Resistively-tapered-dipole electric-field probes up to 40 GHz

An electric-field probe for use as a transfer standard at frequencies up to 40 GHz is developed. The lower frequency cutoff is below 1 MHz. The design is based on the resistively tapered dipole (RTD) probes developed for frequencies up to 18 GHz. Those probes used 8-mm tapered dipoles. In this study, 6-mm, 4-mm, and 2-mm dipoles are used to extend the frequency range. Because the probes are isotropic, have relatively flat frequency response, and have a response which drops off outside their operating frequency range, they could also be used as hazard meters
