On-body antenna for the miners cardiac rhythm sensor

Abstract

The paper continues investigations of antennas for the miner cardiac rhythm sensor. The sensor and the beacon are placed in the battery's box of a miner's lantern. Measurements of cardiac rhythm are based on measurements of reflected microwave energy. The mutual positioning of the battery's box with the sensor and human body is changed continually. Previous investigations have shown that a simple patch antenna is not suitable for the application as its bandwidth is very narrow and sensitive to positions of a body and a lantern. New antenna designs for practical applications have been proposed in the paper. Numerical results and practical advises have been discussed.

The effect of properties of human body on statistical characteristics channel on – body communication

“…Wireless Body Area Networks (WBAN) consist of a number of units placed inside or in proximity of the human body (such as in everyday clothing), and are a natural progression of the WPAN concept [2]. Also known as IEEE 802.15.6, WBAN is a low-frequency technology intended to endow a future generation of shortrange electronics for exchanging information [3] [4]. This paper takes in hand the study one of the body communication (on-body), the channel characterization in the statistical case of human body ,this is will do for standing where two hands along the body , the Characterization of the Radio Channel in On-Body Communication [5].…”
