Abstract :
This paper presents the evaluation of the transmission gain of an ultra wideband antenna on a labtop computer based on the extended Friis´ transmission formula. The matched filter is considered at the receiver side to maximize the SNR for evaluation. This technique gives very accurate results and is very useful for the design and evaluation of UWB impulse radio transmission systems, especially for the evaluation of waveform distortion effects.
