 note = {Impedance of two different kinds of short dipole antenna were measured in the vicinity of the lower hybrid resonance (LHR) frequency in the ionosphere by the sounding rockets. One is a wire antenna of 10 meter tip-to-tip length aboard the K-9M-73 rocket. The other is a short dipole antenna of 10 meter tip-to-tip length aboard the S-520-5 rocket. The experimental results were compared with theoretical values in this paper. Main results are as follows : (1) The impedances of both antenna were capacitive near LHR frequency at the altitude below 24km. (2) The impedance of a short dipole antenna was mainly dependent on the length of an ion sheath surrounding the antenna near LHR frequency in the altitude ranging from 70 to 240km. (3) There seems to be no change of the impedance of the wire antenna as the bias current was varied stepwise from -1.4 to +1.4μA., 資料番号: SA0166140000},
