Abstract
Penggunaan sistem microwave imaging dalam aplikasi pencitraan medis memiliki potensi besar sebagai alternatif dari pencitraan konvesional. Tujuan dari penelitian ini untuk melakukan pencitraan berbasis pada penggunaan perangkat AVA (Antipodal Vivaldi Antenna) dan Circular platform. Proses penelitian dimulai dengan pengkonsepan desain dan simulasi AVA dan circular platform dan dilanjutkan fabrikasi perangkat sesuai dengan konsep yang telah dibuat. Selanjutnya, pengambilan data dilakukan dengan melakukan manipulasi variabel penelitian berupa bahan anomali, media fantom, dan titik koordinat (fantom dan anomali). Kemudian, data yang didapat akan diolah melalui aplikasi Matlab dengan menggunakan algoritma MERIT DMAS. Hasil dari penelitian ini mencakup fabrikasi perangkat AVA dan circular platform, titik frekuensi AVA pada 2,45 GHz, nilai return loss (RL) < -10 dB, nilai VSWR < 2, serta pencitraan yang mampu mengidentifikasi abnormalitas pada setiap manipulasi dari variabel. Kesimpulan dari penelitian ini adalah sistem ini mampu mendeteksi dan memproses sinyal gelombang elektromagnetik dengan baik, serta memberikan hasil pencitraan yang dapat mengidentifikasi abnormalitas pada objek yang diamati.

The use of microwave imaging systems in medical imaging applications has great potential as an alternative to conventional imaging. The purpose of this research is to perform imaging based on the use of the AVA (Antipodal Vivaldi Antenna) device and the circular platform. The research process begins with conceptualizing the design and simulation of AVA and circular platforms and continues with device fabrication according to the concept that has been made. Furthermore, data collection is done by manipulating research variables in the form of anomalous materials, phantom media, and coordinate points (phantom and anomalies). Then, the data obtained will be processed through the Matlab application using the MERIT DMAS algorithm. The results of this study include fabrication of AVA devices and circular platforms, AVA frequency point at 2.45 GHz, return loss (RL) values < -10 dB, VSWR values < 2, and imaging that is able to identify abnormalities in each manipulation of variables. The conclusion of this study is that this system is capable of detecting and processing electromagnetic wave signals properly, as well as providing imaging results that can identify abnormalities in the observed object..
