how to calculate the minimum separation between body and wearable antennas. if it's very small the absorption because of body will be high and and also it effects the input impedance and the radiation pattern of the antenna.
one good approximation is to be keep the distance of (2d2/lambda) from the body for which results are close to a free space response. (all these got from the journals).
can someone tell whether these are correct or not. also what options are there to improve the performance of the antenna in opposite to body direction and keeping the distance minimum from body.(basically min radiation towards the body)
