This paper presents an ultra-wideband (UWB) circularly polarized (CP) multiple-input multiple-output (MIMO) antenna with polarization diversity. The proposed antenna is comprised of a coplanar waveguide feed with modified geometry of the coplanar ground plane. One antenna is design with right-hand CP (RHCP) by altering only the geometry of the left-hand side coplanar ground plane. To achieve the left-hand circular polarization (LHCP) the position of the coplanar ground planes is switched. For p...

In this paper, a novel design of dielectric resonator antenna (DRA) with a reconfigurable radiation pattern capability is presented. Reconfigurability in the azimuth plane is achieved by symmetrically placing six electromagnetic bandgap (EBG) sectors around the DRA. Each sector is composed of twenty-six circular shaped mushroom-like EBG unit cell. In order to achieve 360 degrees pattern reconfigurability with a minimum number of diodes, a network of metallic veins printed on a conductor-...
