Abstract
Limitations of conventional X-ray mammography has induced a recent interest into radio frequency based diagnostic approaches in order to take advantage of the sharpest dielectric contrast between benign and malignant breast tissues in the microwave frequency range [1]. Dielectric contrast is notably higher than the radiographic density exploited by X-ray mammography. Consequences of the superior sensitivity of RF-based techniques can have a huge social and cost impact. By reducing the false response percent, a dramatic reduction of costs for the health system together with a diminution of traumatic experiences for the patients can be achieved. The antenna properties play a fundamental role in the design of an RF breast cancer imaging system. Ultra-wideband (UWB) antennas are suitable candidates for this application as they can offer very large operating band, stable radiation properties and compact dimensions [2]. In the allocation of the operating bandwidth, the bottom edge frequency plays a very critical role. In fact, the RF signal can penetrate more efficiently when radiated at low frequencies. However, this requirement must be compromised with the overall size of the antenna. In order to improve miniaturization and impedance matching, antennas are generally immerged into a coupling medium.
