<para> This letter presents a new design for electromagnetic bandgap (EBG) resonator antennas allowing to create dual-band structures, thus, making it possible to circumvent the problem of their narrow bandwidth. The geometry and working of the antenna are detailed and a design method is proposed. Both the concept and the method are validated by experimental results. </para>
This paper presents a new design for EBG resonator antennas allowing to create dual-band antennas, thus making it possible for some applications to circumvent the problem of their narrow bandwidth. The design and the conception method are detailed and one application example is given
It has appeared very easy to design a circularly polarized EBG antenna using a patch antenna with notches. The results meet to our wishes. The use of several feeds under the EBG material allows to radiate a left or/and a right circular polarization with the same EBG antenna.
