“…It is known that a uniform leaky-wave antenna (LWA) scans the beam in the off-broadside region (a region between

= 0

and

= 90

). Moreover, microstrip LWAs (MLWAs) are planar and low-profile antennas that can be easily integrated with millimeter-wave circuits [ 37 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. Because of the desired radiation characteristics, we found that an LWA would be a simple yet effective solution for beam switching in the millimeter-wave band.…”

Beam-switching is one of the paramount focuses of 28 GHz millimeter-wave 5G devices. In this paper, a one-dimensional (1D) pattern reconfigurable leaky-wave antenna (LWA) was investigated and developed for wireless terminals. In order to provide a cost-effective solution, a uniform half-width LWA was used. The 1D beam-switching LWA was designed using three feed points at three different positions; by selecting the feeds, the direction of the beam can be switched. The antenna can switch the beam in three different directions along the antenna axis, such as backward, broadside, and forward. The 1D beam-switching antenna was fabricated, and because of the wide beamwidth, the measured radiation patterns can fill 128∘ of space (3 dB coverage), from θ = −64∘ to +64∘ at ϕ = 0∘. Following this, two of these antennas were placed at right angles to each other to achieve two-directional (2D) beam switching. The 2D beam-switching antenna pair was also prototyped and tested after integrating them into the ground plane of a wireless device. The antenna is able to point the beam in five different directions; moreover, its beam covers 167∘ (θ = −89∘ to +78∘) at ϕ = 0∘, and 154∘ (θ = −72∘ to +82∘) at ϕ = 90∘.
