Abstract

Invention m. Used in various microwave devices. The purpose of the invention is to narrow the reflection band. The electromagnetic field, existing in a segment of a rectangular waveguide (OGSh) 1, excites a dielectric rod (DS) 2, which excites a disk dielectric resonator (DDR) 3, working in the azimuthal mode of oscillation. The communication of the DSBR with the DC 2 is adjusted by moving the DLPR in the transverse plane. Adjusting the connection of the DS with the OPV 1 — by moving the DS 2 together with the reflector 4 along slot 7 with the screw 8 loose. For additional adjustment of the device to a maximum coefficient. the reflection at the resonant frequency the reflector 4 is moved in the slot 7. The goal is achieved by sequential selection of the connection of DS 2 with DDR and OPV 1 and selection of the distance between the reflector 4 and DS 2. 1 Il. ё (Л г 1 83 со сою

Description

one

The invention relates to the field of radio engineering and can be used in various microwave devices.

The aim of the invention is to narrow the reflection band.

The drawing shows the construction of a resonant reflector.

The resonant reflector contains a segment of a rectangular waveguide 1, a dielectric rod 2 mounted therein, a disk dielectric resonator 3 electromagnetically coupled to the dielectric rod 2, a reflector 4 attached to the foam polystyrene sleeve 5, a stand 6 in which slot 7 is made to enable displacement of the dielectric rod 2 within a segment of a rectangular waveguide 1, and on which is mounted a disk dielectric resonator 3 with the possibility of its transverse movement in a plane, with A rectangular waveguide section 1 incident from the H-plane. For fixing the dielectric rod 2 in the rectangular waveguide section 1, a screw 8 is used, the clamp 9 installed and extending into the rectangular waveguide section 1. Clamp 9 has a pin and a nut (not shown) for mounting it on a stand 6.

Resonant reflector works as follows.

An electromagnetic field existing in a segment of a rectangular waveguide 1 excites a dielectric rod 2, which excites a disk dielectric resonator 3 operating on an azimuthal mode of oscillation. Adjustment of the coupling of a disk dielectric resonator 3 with a dielectric rod 2 is carried out by e. Compiler I. Ivanov Editor L. Gratilo Tehred M. Didig Corrector

c by moving the disk dielectric resonator 3 in the transverse plane, the coupling of the dielectric rod 2 with the length of the rectangular waveguide 1 is adjusted by moving the dielectric rod 2 together with the reflector 4 along the slit 7 with a weakened screw 8, to further adjust the device to the maximum reflection coefficient at the resonant frequency, the reflector 4 can be moved in the slot 7. The purpose of the invention is achieved by successively selecting a dielectric connection. of rod 2 with the dielectric resonator disc 3 and the segment of the rectangular waveguide 1 and selection of the distance between the reflector 4 and the dielectric rod 2.
