Title:
MICROWAVE DEVICE
Document Type and Number:
Japanese Patent JP2020072354
Kind Code:
A
Abstract:
To provide a microwave device with a simple structure, which can suppress variations in performance.SOLUTION: A microwave device 100 includes a microwave generator 10, a power feeding path portion 20 that guides microwaves, and a resonator 30 having therein a cavity 30a in which microwaves are introduced. The power feeding path portion 20 includes a center conductor 21, an insulator, and an outer conductor. An electromagnetic field of a TM010 mode or a TM110 mode is excited in the cavity 30a. The terminal portion of the outer conductor is electrically connected to one of an upper wall portion 32 and a lower wall portion 33 of the resonator 30. The center conductor 21 includes an introduction portion 21a that introduces microwaves into the cavity 30a. The introduction portion 21a penetrates a hole 32a formed in the one wall portion in a state of being electrically insulated from the one wall portion to project into the cavity 30a, and extends parallel to a central axis O in the vicinity of an inner side surface 30b of the resonator 30.SELECTED DRAWING: Figure 1
