Distributed radio frequency or microwave thawing device

A distributed radio frequency or microwave thawing device, comprising one or more thawing units,

• wherein each of the one or more thawing units comprises a power supply module, a control unit, a radio frequency or microwave generation module, a measuring unit, an antenna means and a thawing chamber;
• the power supply module, the radio frequency or microwave generation module, the measuring unit and the antenna means are connected in sequence;
• the control unit is connected to the power supply module and the measuring unit, respectively;
• the antenna means is disposed in the thawing chamber, and the antenna means comprises a first antenna group and a second antenna group, the first antenna group comprises one or more first antennas, the second antenna group comprises one or more second antennas, the one or more first antennas and the one or more second antennas are arranged in pairs, pairs of first antenna and second antenna are arranged in parallel and opposite to each other and form an antenna unit, a plurality of antenna units are arranged side by side, and the thawing chamber comprises one or more rows of antenna units;
• a working bin is formed between the first antenna group and the second antenna group;
• a number of each of the radio frequency or microwave generation module and the measuring unit is one or more;
• and
• the radio frequency or microwave generation module and the measuring unit are connected to the antenna units one to one, wherein balanced feeding is adopted to ensure that feeding points of the first antenna in the first antenna group have a voltage amplitude difference less than 50% and a phase difference within a range of 0-90°;
• feeding points of the second antenna in the second antenna group have a voltage amplitude difference less than 50% and a phase difference within a range of 0-90°;
• and feeding points of the first antenna and the second antenna of the antenna unit have a voltage amplitude difference less than 70% and a phase difference within a range of 80-280°.
