“…Various beam‐steering techniques have been developed including the use of shorting pins , parasitic radiators , and reconfigurable methods . Another example for a reconfigurable design are pixel antennas using several kinds of parasitic pixel layers above the radiating element for implementing beam steering . These pixel antennas are highly flexible with respect to frequency tuning, pattern diversity, and polarization adaptation.…”

“…Recent investigations on reconfigurable beam steering antennas are mainly focused on microstrip patch antennas due to their compact, simple, and low cost design. However, little attention has been paid to reconfigurable tapered slot antennas using parasitic pixel layers although they have the same advantages as planar antennas.…”

A tapered slot antenna element capable of reconfiguring its beam direction is presented. As the basic element, a Vivaldi antenna fed by a substrate integrated waveguide is chosen. The Vivaldi antenna is complemented by a parasitic planar array of small metallic patches placed in front of its aperture and by corrugated edges of the Vivaldi antenna's arms to provide reconfiguration capabilities. The proposed antenna's beam can be steered in five directions by configuring the interconnections of the parasitic patches and by activation/deactivation of the corrugated edges in the antenna arms. The antenna steers the radiation beam over ±30° in E plane and operates in the frequency band of 6.0–6.5 GHz. The measured gain at 6.25 GHz for 0°, ±15°, and ±30° beam direction of the antenna with ideal switches, is 8.4 dBi, 7.5 dBi, and 6.7 dBi, respectively. © 2017 Wiley Periodicals, Inc.

“…The reconfigurable antennas can function for multiple operations with a single antenna. Reconfigurable antennas are defined with the capability of modifying one or more antenna parameters without affecting other antenna properties [1][2][3][4]. UWB antennas suffer from electromagnetic interferences due to narrowband applications in 3.1-10.6 GHz frequency range.…”

“…Recently, pixel patches are highly appreciated in the design of reconfigurable antennas. Pixel shaped parasitic elements have been used to steer the antenna beam without using phase shifter in [1]. For pattern reconfigurable applications of a steerable beam in desired directions and for multi-function operations, a reconfigurable parasitic pixel surface has been utilized [2,3].…”

A microstrip antenna with a pixel ground structure for single and multiband frequency reconfigurable applications is presented. The partial ground structure of the primary antenna is converted into pixel shapes which produce single and multiband frequency reconfigurable characteristics by the means of RF switches. The designed antenna operations are switchable over multiband, single frequency band and UWB spectrum with the distinct configuration of RF switches. Three cases of RF switch configurations have been demonstrated with their simulated and measured results to verify the reconfigurable characteristics.

In this article, a reconfigurable cross parasitic antenna is proposed to achieve complete azimuthal beam scanning and tunable beamwidth in the E-and H-plane. The antenna consists of a square-shaped driven element and four size-tunable parasitic elements placed on each side of the driven element. Each tunable parasitic element is composed of a hexagonal slot loaded with two varactor diodes. The tunable parasitic element shows dual-resonance behavior and hence its effective electrical size can be controlled with respect to the driven element. The radiated beam of the cross antenna is continuously scanned in the elevation plane from θ = 0 to 10.8 , 0 to 32.4 , and 0 to 40 in ϕ = (0 , 180 ), (45 , 135 , 225 , 315 ), and (90 , 270 ) planes, respectively. Moreover, the 3-dB beamwidth of the cross antenna is continuously tuned from 65 to 152 and from 64 to 116 in the E-and H-plane, respectively. The antenna shows good impedance matching in all the operating modes with −10 dB bandwidth from 2.43 to 2.47 GHz. A prototype of the antenna is fabricated to experimentally verify the simulated reflection and radiation characteristics.
