The effect of the human body on radiation properties of small-sized communication systems

The results are presented of an experimental investigation of the effect of the human body on small-sized radio communication systems equipped with whip antennas. For a frequency range of approximately 30 to 150 MHz, the qualitative relations are defined between, on the one band, the space configuration of an antenna system and the operator's body, and, on the other hand, electrical parameters such as impedance, radiation pattern, and especially gain.
