Effect of Human Body on Radiation Pattern of Wireless Microphone
Naoto Kogo, Hiroyuki Hamazumi (NHK)
Abstract (in Japanese) (See Japanese page) 
(in English) The wireless microphone is used in the 700MHz band and used for program productions, concerts, stage dramas, and so on. We designed a helical antenna and a 1/4 wavelength monopole antenna with a metallic case as a handheld type and body-pack type of wireless microphones and calculated the characteristics of the antenna with a numerical model of the human body. To investigate the effect of the human body on the performance of the antenna, we calculated the antenna gain and radiation patterns when the antenna is in close proximity to the breast or waist. From these results, we found that the distance between the antenna and human-body and the height of the antenna are significant parameters for the radiation patterns of antennas.
