Beam Steering of Patch Antenna Radiation using Mechanical Meta-Structure

Attempt is made to modify the radiation pattern of a patch antenna using a meta-structure consisting of an array of monopole antennas in the near field. The effect of the metastructure on the radiation characteristics of the patch antenna, for different angular arrangements of the metastructure plates, has been experimentally studied.

Tunable beam steering enabled by graphene metamaterials.

We demonstrate tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. The effective refractive index of such metamaterials can be manipulated by changing the chemical potential of each graphene layer. This can arbitrarily tailor the spatial distribution of the phase of the transmitted beam, providing mechanisms for active beam steering. Three dif...

Highly sensitive beam steering with plasmonic antenna

In this work, we design and study a highly sensitive beam steering device that integrates a spiral plasmonic antenna with a subwavelength metallic waveguide. The short effective wavelength of the surface plasmon polaritons (SPPs) mode supported by the metallic waveguide is exploited to dramatically miniaturize the device and improve the sensitivity of the beam steering. Through introducing a ti...

Design of Microstrip Patch Antenna by Introducing Defected Ground Structure

This paper proposes a novel Inset Feed Microstrip patch antenna with Z and F shape defect in ground plane. Initially simple inset feed rectangular Patch Antenna is designed and results are analyzed. Further this design is modified by etching Z and F shaped defect on ground plane. Defected Ground Structure is studied to enhance the performance parameters of microstrip patch antenna.
