Abstract :
A simple technique is presented to derive lower bounds for the radiation Q of electrically small devices. The new technique is applicable to any topology. It takes into account possible currents actually flowing on the device. Moreover, it allows to prove several well-known minimum radiation Q´s for basic topologies.
