We present the numerical parametric study of a reconfigurable plasma antenna array (PAA) composed of a metallic half-wavelength dipole and a set of cylindrical plasma discharges arranged in a planar square lattice. Our results, obtained with the linear embedding via Green’s operators (LEGO) method, indicate that beam-forming and beam-steering functionality can be achieved and controlled by appr...
We have proposed design of ESPAR (Electronically Steerable Parasitic Array Radiator) antenna that is capable of electronic beam steering in order to avoid interference, null is placed in direction of interference source whereas maxima is placed in direction of desired signal source. Paper includes formulation of mathematical model, simulation and later designing of ESPAR antenna capable of dyna...
Coordinated Multi-Point transmission/reception (CoMP) can increase the performance of the cell edge users, the spectrum efficiency and mitigate the inter-cell interference among cells. In the CoMP scenario, several base stations which usually need satisfy the cooperating condition serve a single or several cell-edge users cooperatively. As we know, the CoMP techniques can be characterized into ...
A novel design method of simultaneous beam forming and focusing using a checkerboard anisotropic surface is proposed verified in this paper. The multibeam control regardless far near regions can easily be achieved through rearrangement the structure. unit cell utilized consists two identical metallic structures divided by dielectric material. When EM wave with circular polarization (CP) inciden...
