Effect of Human Posture on Radiation Pattern of Transceiver in VHF and UHF Bands
Naoto Kogo, Tetsuomi Ikeda (NHK)
Abstract (in Japanese) (See Japanese page) 
(in English) The push-to-talk communication line for broadcasting services is used in the VHF band (165 MHz) and UHF band (460 MHz) in Japan. It is used for communication between staff during news gathering, television and radio program production, and so on. We designed a helical antenna with a metallic case as a handheld type transceiver and calculated the characteristics of the antenna with a numerical model of the human body. To investigate the effect of the human posture on the performance of the antenna, we calculated the antenna gain and radiation patterns when the antenna is in close proximity to the face. From these results, we found that the radiation patterns between with and without consideration of the arm and the human posture are significantly different in VHF band, however, the differences of the radiation patterns due to the arm are significant and the human posture are small in UHF band.
