“…The phased-array technique is widely employed in conventional beamsweeping antenna designs; however, this method may result in a large-size structure. [3][4][5][6] Meanwhile, antennas based on the Butler matrix can also achieve beamforming behavior. These designs could generate beams with different radiant angles with various input amplitude and phase, but usually with a complex structure.…”

In this work, a simple and compact reconfigurable antenna, whose radiation direction and beamwidth can be manipulated, is proposed based on active frequency-selective surfaces (AFSSs). This design is completed by using a monopole antenna and six reflective AFSS screens, while its reconfigurable behavior is obtained by employing semiconductor switches. By applying different biasing voltages on the diode switches, the operating state of the AFSS screens can be configurated; therefore, the radiation direction and beamwidth of the monopole antenna can be controlled. From 1.8 to 2 GHz, the omnidirectional scanning response can be achieved at xoy-plane with the step of 60 and the maximum radiant efficiency is 96%. Furthermore, the 3 dB beamwidth can also be adjusted from 176 to 120 with the measured gains of 4.58-6.53 dB.The diameter of this structure is only 50 mm, which is a relatively small structural size for an omnidirectional beam-sweeping antenna. Finally, the proposed design is validated by numerical simulations and experimental measurements.

“…For instance, beam switch antenna can be designed using conventional phased array antennas. [8][9][10][11] However, a phased array antenna needs an active circuit and, in many cases, a digital phase shifter, which makes the antenna complex and expensive. Beam switch antenna based on the lens structure shows excellent potential for high directivity radiation pattern.…”

A new beam switch antenna based on a composite right/left‐handed (CRLH) Butler matrix is presented and experimentally validated. The CRLH transmission line (TL) is proposed to increase the number of beams. The proposed CRLH TL has more than 100° phase difference using variable bias voltages. Different combinations of phase shifts are achieved by applying different bias voltages between 0 and 8 V. The CRLH TL is added to the conventional Butler matrix to increase the progressive phase difference between adjacent ports, and consequently, the beam pattern. A 5° beam resolution within a spatial range of 100° is achieved. The measurement results are in good agreement with the simulations.

“…Radar and satellite systems operating in the K-band are widely used in communication services, and depending on the application, specific antenna design is required. For long distance communication and accurate speed detection, a high gain and narrow beam width antenna is preferred [1,2]. For these reasons, leaky-wave antennas have attracted much attention due to their high gain, simple feeding structure, unique frequency beam scanning capability, and wide operational bandwidth [3,4].…”

A periodic millimeter wave leaky-wave antenna (LWA), which has two different types of radiator elements that enable backward to forward radiation, is proposed. The unit-cell of the LWA consists of two quarter-wavelength microstrip lines and two corrugated substrate integrated waveguide (CSIW) cells with S-shaped quarter-wavelength open-circuit stubs. In addition to two parallel edge radiators, a single etched transverse slot with a tilt angle acts as an ancillary radiator, which ensures impedance matching in a large frequency range and achieves the backward to forward scanning. We analyze the proposed design through simulations, characterize a fabricated prototype, and find it to have good radiation properties including broad impedance bandwidth. The measurement results show a high peak gain from 11 to 15.8 dBi with a large scanning angle range from −34 • to +22 • in the K-band operating frequency range.
