Objective:
A 2.45 GHz microstrip applicator using single rectangle sheet structure is presented.
Methods:
Based on the radiant principle of microstrip antenna, the applicator's parameter is designed and the simulating model is set and optimized in HFSS.
Results:
Measured by network analyzer, the technical target of this applicator is complied with design demand. During irradiation experiment, based on 30 W power, 30 mm radiation distance and 15 min duration experiment condition, the thermal field distribution map of phantom is obtained from the far-infrared image instrument. The 3D map shows that the region of thermal field centre has small radius and deep heat penetration.
Conclusion:
The microwave energy from this applicator can reach the tumor in superficial layer without heat injuring normal tissue around it.
