英文摘要： In microwave hyperthermia for deep located tumor, the key factor affecting the quality of therapy is the reasonable distribution of energy delivered on the tumor tissue. How to improve the radiation efficiency of antenna and make the transmitted power accumulated in the deep tumor area is the key technology of microwave hyperthermia. In this project, we intent to utilize the theory of power transmission in network to design near-field focusing antenn.The excitation parameters of the transmitting array can be obtained by calculating the scattering parameters and the best transmission efficiency of the networks. The relationship between the focusing cabability and the form and number and locations and distances of the antennae is investigated.The dependence of focusing volume on form and numbers of the receiving antenna is also analyzed. Based on the research in the project, the microwave hyperthermia treatment planning can be quickly maded based on the designed near-field focusing antenna for different case of tumor hyperthermia.
