Ultra wide band low-power amplifier integrated on miniaturized antenna for biomedical applications

This work presents the design and the manufacturing of an ultra wide band amplifier integrated with a low impedance antenna for Biomedical applications. The amplifier operates from 1.5GHz up to 3.5GHz that gives the advantage of having high resolution radar system. The amplifier has a gain of 10dB with input reflection coefficient less −5dB and serves as a matching network between the 50Ω input and the low impedance antenna. The chip consumes low power of 56mW and has an area of 0.689 mm
