Patent number: 10559885Abstract: 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.Type: GrantFiled: January 24, 2019Date of Patent: February 11, 2020Assignee: Associated Universities, Inc.Inventor: Matthew Alexander Morgan

Publication number: 20190253033Abstract: Reflectionless transmission line filters, as well as a method for designing such filters is disclosed. These filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications. The insertion of additional transmission line sections that change the phase response of the circuit without altering the amplitude response preferably allows follow-up transmission line identities to be applied in order to arrive at a more easily manufacturable filter topology. This facilitates their application over a higher frequency range the solely lumped-element circuits.Type: ApplicationFiled: April 24, 2019Publication date: August 15, 2019Inventor: Matthew Alexander Morgan

Patent number: 10374577Abstract: Reflectionless low-pass, high-pass, band-pass, band-stop, all-pass, all-stop, and multi-band filters, as well as a method for designing such filters is disclosed, along with a method of enhancing the performance of such filters through the use of unmatched sub-networks to realize an optimal frequency response, such as the Chebyshev equal-ripple response. These filters preferably function by absorbing the stop-band portion of the spectrum rather than reflecting it back to the source, which has significant advantages in many different applications. The unmatched sub-networks preferably offer additional degrees of freedom by which element values can be assigned to realize improved cutoff sharpness, stop-band rejection, or other measures of performance. The elements of the filter may be physical passive elements, or synthesized with active circuits, potentially realizing even negative element-values for improved performance.Type: GrantFiled: November 14, 2017Date of Patent: August 6, 2019Assignee: Associated Universities, Inc.Inventor: Matthew Alexander Morgan
