Abstract :
In this paper, we investigate the behavior of a switched oscillator (SWO) taking into account the frequency-dependency of the antenna´s input impedance. The analysis is performed using the chain-parameter (ABCD) representation of the system which allows obtaining a semi-analytical solution suitable for the design and optimization of the SWO. The proposed approach is applied to the analysis of an SWO connected to a monopole antenna for which the transfer function and the radiated fields in frequency- and time-domain are evaluated.
