The Design of a Resistively Loaded Bowtie Antenna for Applications in Breast Cancer Detection Systems

Near field imaging using microwaves in medical applications has been found by numerous researchers to perform well in comparison to more established screening tools such as Magnetic Resonance Imaging (MRI), digital mammography and ultrasound. This work documents the development of a resistively-loaded Bowtie antenna for microwave imaging applications such as breast cancer detection. The application has similarities to Ground Penetrating Radar (GPR) but operates at higher frequencies with minimal late-ringing and internal reflections. Genetic algorithms were used to optimize the antenna design and give very promising outcomes. This research will be taken forward with the submission of a breast cancer campaign grant application.
