An apparatus to create uniform electric and magnetic-field distribution as zeroth-order resonance in a waveguide and a cavity according to an embodiment of the present invention includes a rectangular waveguide with a rectangular-shaped cross section comprising a cavity in the inside, and a conductive helical wire inserted into the cavity of the waveguide, wherein the main body of the conductive helical wire does not contact the inner surfaces of the waveguide at a predetermined gap, and both ends of the conductive helical wire are short-circuited to the inner surface of the waveguide, so as to create a uniform electric field and magnetic field throughout the entire waveguide.

Apparatus to create uniform electric-field and magnetic-field distribution as metamaterial zeroth-order resonance in waveguide and cavity and leaky-wave waveguide antenna for high directivity radiation

A multi input multi output (MIMO) antenna with no phase change is provided. The MIMO antenna having no phase change constituting one antenna structure overall, wherein unit structures at both sides are symmetrical to each other in a meander form with respect to the center; the unit structures having the meander form are connected to a ground plate by using as a medium power feeding unitsandsupplying an electric energy to the respective unit structures; and the unit structures are installed with a three-dimensional structure, being adjacent to the ground plate.
