The development of an L-band radiometer dual-mode horn
By: Bailey, M.;
1975 / IEEE
This item was taken from the IEEE Periodical ' The development of an L-band radiometer dual-mode horn ' A conical circularly polarized dual-mode horn, designed for the frequency range of 1400-1460 MHz, is described. This electrically shorter version of the Potter horn yields circularly symmetrical patterns over a broader frequency range (approaching 10 percent). A technique is described for matching the input over the design bandwidth with a VSWR < 1.05.
