An ultra-wideband (UWB) microwave system for breast cancer detection is presented. The proposed system includes monocycle pulse generator, antipodal Vivaldi antenna, breast model, and calibration algorithm for tumor detection. Firstly, our pulse generator employs transmission gate in glitch generator to achieve several advantages such as low power consumption and low ringing level. Secondly, the antipodal Vivaldi antenna is designed assuming FR4 dielectric substrate material, and developed antenna element (80 × 80 mm2) features a −10 dB return loss and bandwidth ranges from 2.3 GHz to more than 11 GHz. Thirdly, the phantom breast can be modeled as a layer of skin, fat, and then tumor is inserted in this layer. Finally, subtract and add algorithm (SAD) is used as a calibration algorithm in tumor detection system. The proposed system suggested that horizontal antenna position with 90° between transmitting and receiving antennas is localized as a suitable antenna position with different rotating location and a 0.5 cm near to phantom. The mean advantages of this localization and tracking position around breast is a high received power signal approximately around mv as a higher recognized signal in tumor detection. Using our proposed system we can detect tumor in 5 mm diameter.

“…One of the most important concerns in IR-UWB design is to fulfill these regulations. Hence significant attention has been devoted to the design of the UWB pulse generator which is the key block in determining the power spectral density (PSD) of the IR-UWB signal [7][8][9][10][11].

“…Previously reported UWB pulse generators usually offer fixed pulse amplitudes and thus for each specific application a specific design is preferred for optimum performance [7]. Furthermore, several short range wireless applications, such as wireless ultrasound video streaming, prefer adaptively adjustable data rate and signal strength to maintain the communication quality while the communication distance is varying due to the movements of the ultrasound probe or the body of the patient [12].…”

This paper presents an ultra wideband pulse generator topology featuring adaptive control of power spectral density for a broad range of applications with different data rate requirements. The adaptivity is accomplished by employing a limited monocycle pre-charge approach to control the energy used for pulse generation at different desired data rates. By doing so the need for tuning circuits is eliminated and the radiated power is maintained at the highest level allowed by FCC. A prototype pulse generator has been implemented using the UMC 180 nm CMOS process for validation. The measured results show that the pulse generator can be used for a wide pulse repetition rate range from 100 Mpps to 1 Gpps. In addition, the pulse generator consumes 0.76 pJ/pulse at 1 Gpps, equivalent to 760 µW, and has a compact size of 0.09 mm 2 .
