Abstract

The invention discloses a wearable microwave thermal therapy device and an array antenna stack thereof. The array antenna stack comprises microstrip patch antenna units and coaxial input lines, wherein the microstrip patch antenna units are annularly arranged along different pitch angles, and the phase of each microstrip patch antenna unit can be adjusted to any value between 0-360 deg; a centralantenna of each microstrip patch antenna unit is arranged at the middle point of a breast model; a first antenna stack comprises a plurality of first antenna units which are annularly distributed, anda pitch angle between each first antenna unit and the corresponding central antenna is a first angle; a second antenna stack comprises a plurality of second antenna units which are annularly distributed, and a pitch angle between each second antenna unit and the corresponding central antenna is a second angle; and the number of the coaxial input lines is equal to that of the microstrip patch antenna units, and the coaxial input lines are connected with the microstrip patch antenna units in a one-to-one correspondence manner. The technical problem that existing microwave thermal therapy equipment for breast cancer treatment cannot achieve large-range treatment is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a wearable microwave thermotherapy equipment and an array antenna group thereof. Background technique [0002] Microwave hyperthermia has gradually become an important technology for treating tumors, and the most important link in microwave hyperthermia technology is the design of hyperthermia antenna, which has great advantages in terms of treatment range, treatment time, influence on normal tissues and system stability. played a key role. Microwave hyperthermia is divided into external hyperthermia, internal intervention or insertion hyperthermia. External hyperthermia refers to the hyperthermia in which the microwave radiation antenna is located outside the body. It is mainly used to treat diseased tissues located on the surface and superficial layers of the body. The antenna designed for breast cancer microwave hyperthermia is an extracorporeal hyperthermia antenna. It is a...
