T-matched dipole antenna integrated in electrically small body-worn wireless sensor node

• A 2.4 GHz antenna for an electrically small body-worn sensor node is   presented. Usually, unbalanced antennas are used in such applications. Implementing a balanced antenna in a small node deployed on the body is problematic from the points of view of both design and   characterisation. A solution using a T-matched dipole integrated in the   node housing is presented. Techniques for characterisation both in free space and on the body are described. Besides antenna port impedance and radiation efficiency, radiated power and radiation patterns of the active antenna fed by a transceiver in a fully functional sensor node are measured. The benefits and drawbacks of the chosen antenna design and characterisation techniques are discussed.
