Abstract:
OBJECTIVEA 2.45 GHz microstrip applicator using single rectangle sheet structure is presented.
METHODSBased on the radiant principle of microstrip antenna, the applicator's parameter is designed and the simulating model is set and optimized in HFSS.
RESULTSMeasured 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.
CONCLUSIONThe microwave energy from this applicator can reach the tumor in superficial layer without heat injuring normal tissue around it.
