Title:
ELECTRIC ADJUSTING ANTENNA STRUCTURE FOR CHANGING MICROWAVE ELECTRIC FIELD DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO/2020/249082
Kind Code:
A1
Abstract:
Provided is an electric adjusting antenna structure for changing microwave electric field distribution, wherein, comprising a microwave oven cavity (101) and a radio frequency antenna (102), one end of the radio frequency antenna (102) is disposed in the microwave oven cavity (101), the other end is connected to a transmission mechanism (103), the transmission mechanism (103) is connected to a driving device (104), the transmission mechanism (103) is driven by the driving device (104) to change the relative position of the radio frequency antenna (102) to the microwave oven cavity (101), for a changing load of food placed in the microwave oven cavity (101), the load matching is changed by using the electric adjusting antenna structure such that the standing wave VSWR can be optimal,
and therefore, the microwave energy is converted with the highest efficiency and is absorbed by the load of food.
