Abstract

An antenna arrangement combined with a transistor, characterized in that the transistor is connected at the base of the antenna, directly and without adaptation circuit or longer supply lines between the input terminals of the antenna (in asymmetric antennas, through of a conductive surface between the conductive surface and the input terminal of the antenna, and in symmetrical antennas, at the symmetrical power point between the symmetrical input terminals), and because the antenna, by appropriate choice of its shape and its dimensions, is realized in such a way that the antenna, in the range of prescribed operating frequency, has between its input terminals a complex impedance affected by an inductive phase angle and that is equal or approximately equal to the impedance zaopt optimal for the transistor in question, connecting the emitter and collector of the transistor, in the case of a transmitting antenna, directly to the antenna, and if the optimal impedance zaopt is the load resistance of the collector circuit, to which the transistor gives the maximum effective power, or, in the case of a receiving antenna, the emitter and the base are connected directly to the antenna, and the optimum impedance zaopt the internal resistance of the receiving antenna, which acts as a voltage source, to which the receiving facility has the minimum buzzing rate (minimum equivalent buzzing temperature).
