“…Different methods that used to control the phase compensation of the transmitarray elements are discussed in details in [7][8][9]. The radiation characteristics of different transmitarray designs using dipoles, microstrip patch, and dielectric resonator antenna are investigated in [10][11][12][13][14]. Multifocal optical lenses are artificial lenses designed to provide simultaneous focus at different distances in contrast to mono-focal lenses which only one focal point [15].…”

In this paper, the design of single-focused and dual-focused transmitarray antennas in the near-field (NF) or/and far-field (FF) applications are proposed. A unit-cell element consists of a dielectric square box with four identical holes is used. The phase compensation of the unit-cell elements depends on changing the hole radii according to the position of the unit-cell element, the feeding horn, and the beam direction. The radiation characteristics of 13×13 unit-cell elements transmitarray antenna focused in the near-and the far-field regions are investigated. A single structure, dual-focused transmitarray is designed using a chess-board arrangement of the unit-cell elements. Double-focused transmitarray antennas for FF/FF, FF/NF, and NF/NF are designed and investigated. The phase distributions and the corresponding hole radii for different configurations of the dual-focused transmitarray antennas are presented. The radiation characteristics of different array configurations are investigated and analyzed using a full-wave simulator CST Microwave Studio.

The concept of a reconfigurable patch antenna array is presented in this article. Configurability is achieved using liquid metal alloy which fills necessary milled channels in the antenna structure. A single patch antenna and three patch antenna array are simulated and measured in this work. Matching and radiation properties in the frequency range from 4 to 10 GHz are presented. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2462–2464, 2014
