View page
US Patent:
41339975, Jan 9, 1979
Filed:
Feb 9, 1977
Appl. No.:
5/766854
Inventors:
Richard A. Thuleen - Minneapolis MN
Assignee:
Litton Systems, Inc. - Beverly Hills CA
International Classification:
H05B 906
US Classification:
219 1055F
Abstract:
A microwave oven providing for the introduction of microwave energy to a cooking cavity through each of two opposite side walls is disclosed. Each of two side walls includes a window portion and an energy feed box is mounted to each side wall adjacent the window portions. Microwave energy is supplied to the feed boxes through a waveguide from a single microwave source, the waveguide being elongated to provide a lengthy transmission path for the energy believed to produce a long lines effect. The feed system provides enhanced pattern distribution in the cavity and for optimal matching of the waveguide to the cavity with a minimum of tuning.
