Abstract :
This paper describes the implementation of an active integrated spiral antenna for UWB (ultra-wideband) applications. By integrating a low-noise amplifier with antenna, the voltage standing wave ratio (VSWR) can be kept low for a large bandwidth, resulting in an improved spiral antenna performance for UWB. For the designed circuit in the UWB frequency range (3.1-10.6 GHz), the gain of the LNA is better than 13dB, its noise figure is less than 3dB, S11 and S22 are less than -13dB, respectively.
