A developed excitation law for beam forming and steering applied to a novel electromagnetic band gap antenna

This paper presents an experimental validation of a developed feeding technique applied to a novel antenna system called `electromagnetic band gap matrix antenna´. The experimental validation will not only demonstrate the theoretical concept of the antenna, but it will also show the efficiency of applying a developed excitation law which enables us to obtain a sectorial radiation pattern presenting a quasi-constant gain over an angular range of 18° with low side lobes level less than -20 dB. The feeding technique process is described in this paper and some experimental results are presented to demonstrate the beam forming and steering capabilities of the matrix antenna.
