Abstract

Electrically conductive polymers can combine the advantage of plastic processing with the unique electrical properties which are usually found in metals. This article presents a feasibility study of an electrically conductive plastic for hearing aid antennas. Focus will be placed to critically analyse the electrical properties of the potential conductive plastic in a two component injection moulding process chain. The purpose of this experimental study is to mimic the real scenario in a hearing aid device and conclude the antenna’s efficiency based on the results obtained with OTA (over the air) 3D measuring system in comparison with an ideal copper antenna at 2.4 GHz. An analysis of the association between the conductive plastic processing parameters in regards to its electrical performance is discussed and evaluated.
