Abstract :
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.
