Presented are the effects of a combination consisting of an antenna and tunnel diodes. This is a first report explaining some fundamental rules in respect to the application of tunnel diodes with antennas also the corresponding impedance measurement techniques are described. Part I of this treatment is primarily concerned with the stability problems involved in avoiding self-excitation phenomena within the system. Part II discusses the basic questions concerning the measurement of input impedance. A folded unipole with a tunnel diode at the top of the radiator is studied experimentally as an example. The measurement of impedances with negative resistances by using slotted line techniques is also described.
