Dalam kertas ini, analisis, reka bentuk dan keputusan eksperimen aplikator tatasusunan aktif dibentangkan. Teknik mengunci suntikan digunakan untuk mengubah magnitud sumber gelombang mikro supaya stereng medan berhampiran dapat dicapai. Teknik ini boleh digunakan untuk rawatan kanser hipertermia gelombang mikro untuk menyediakan taburan suhu seragam yang besar. Kerumitan sistem boleh dikurangkan dengan menggunakan teknik ini. Kajian menunjukkan bahawa taburan suhu boleh dikawal dengan mengubah indeks modulasi, frekuensi modulasi dan fasa awal isyarat modulasi. Pengagihan suhu juga dipengaruhi oleh konfigurasi aplikator, jarak antara aplikator dan masa pemanasan. Pendekatan Spectral Domain digunakan untuk menganalisis medan dekat dan kemudian data medan dekat digunakan untuk mencari taburan suhu dengan menggunakan kaedah Perbezaan Terhingga. Kajian ini dijalankan pada frekuensi 2,450 MHz. Reka bentuk ini berguna untuk pelaksanaan aplikator boleh dikendalikan kos rendah.

Abstract: In this paper, the analysis, design and experimental results of active array applicator are presented. The injection-locking technique is used to alter the magnitude of the microwave sources so that the steering of near fields can be achieved. This technique can be applied for microwave hyperthermia cancer treatment to provide the large uniform temperature distribution. The complexity of the system can be reduced by using this technique. The study shows that the temperature distribution can be controlled by varying the modulation index, modulating frequency and initial phase of modulating signal. The temperature distribution is also affected by applicator configuration, spacing between applicators, and heating time. The Spectral Domain approach is used to analyze the near field and then the near field data are used to find the temperature distribution by using the Finite Difference method. The study is carried out at frequency of 2,450 MHz. This design is useful for implementation of the low cost steerable applicator.
