Abstract:
A TEM line to double-ridged waveguide launcher and horn antenna are disclosed. The launcher uses multiple probes or one or more wide-aspect probes across the ridge gap to minimize spreading inductance and a TEM combiner or matching taper to match the impedance of the probes over a broad bandwidth. The horn uses a power-law scaling of gap height relative to the other dimensions of the horn's taper in order to provide a monotonic decrease of cutoff frequencies in all high-order modes. Both of these techniques permit the implementation of ultra-wideband designs at high frequencies where fabrication tolerances are most difficult to meet.

Claim (Index 8):
An assembly comprising a Transverse Electric and Magnetic (TEM) transmission line (TEM line) or quasi-TEM line to double-ridged waveguide launcher and a horn antenna;\n the launcher comprising:\n one or more probes extending across the gap in a double-ridged waveguide; \n a waveguide backshort; and \n a TEM combiner or matching taper; \n wherein one or more of the ridges of the double-ridged waveguide do not extend into the backshort; \n wherein the backshort provides a near open-circuit to the probes over a wide range of frequencies; \n wherein each probe is adapted to minimize spreading inductance of currents in the launcher across a width of the ridges of the double-ridged waveguide; and \n wherein the TEM combiner matches the collective impedance of the probes to the TEM line; and \n the horn antenna comprising:\n a double-ridged waveguide input; and \n a radiating aperture; \n wherein the waveguide outer dimensions and ridge width increase smoothly and monotonically over a length of the horn; and \n wherein the gap dimension scales according to a power law relative to one or more of the other waveguide dimensions over a majority of the length of the horn.
