joshuacp said:I think you can refer to some papers with such title, the effect of the body to the performance of the antenna in IEEE. The effect of the body to the performance of the antenna is a hot subject in celular antenna.
I agree with you that all the discussion is about interaction between antenas and human body, but the last guy mentioned "safety" so I though he was concerned with harmful effects, sorry if I misunderstood.spikeyang said:I think he is not asking whether radiation will do harm to human body but how to make a insensitive antenna.
I have tested some stub antenna's far field strength.It should be noted that as the frequency as high as 2GHz ,the H plane filed distribution is not a cirlce at all. With hand or head effect, the antenna directivity would get worse. In some direction the E strength is 20 dB lower than average. Helical antenna is not so good as in lower band.
I just think you should increase the radiation area of the antenna, choose some other form antenna shape to avoid the human body effects.
