Abstract :
The letter presents the results of an investigation aimed at minimising losses in thick-film screen-printed microstrip circuits. The Q factor of closed resonators of 30 ¿ and 50 ¿ impedances has been measured over the 1¿10 GHz range. It is found that the effective r.f. conductivity is about one half that of bulk material over the major portion of the band considered.
