“…For this purpure, small broadband resonators could be arranged in linear/planar phased array configurations. Moreover, end-fire arrays are more suitable for achieving full coverage than typical antennas including patch, monopole, or slot antennas [15][16][17][18].…”

Broadband/multiband phased array antennas with wide-scan and smart beam-steering are desirable to meet the capacity and security requirements of 5G and beyond. This paper discusses the characteristics of a new beam-steerable phased array design having broadband/multiband function for 5G and beyond communications. The discussion is focused on smartphones, due to their small size and complexity. The design procedure is straightforward and accomplished on a mainboard of future smart handheld devices. The introduced phased array design involves eight Yagi-dipole resonators with a 1×8 linear form. The resonators have small sizes with discrete feedings. For -10 dB, the design represents dual broad bands including 22-33 GHz and 38-65 GHz covering multiple bands in the 5G and beyond spectrums.

In this paper, we demonstrate a V-band planar micromachined helical antenna (PHA) with end-fire radiation on the glass substrate. The planar rectangular helical configuration is realized using the novel through-glass silicon via (TGSV) technology. The proposed micromachined antenna is designed and fabricated on a borosilicate glass substrate of thickness 350 µm, which has a very low-dielectric loss compared to silicon at millimeter-wave bands. The proposed PHA is fed by a microstrip line, and the planar helical configuration with 3.25 turns with a truncated ground plane is designed for achieving wideband end-fire radiation with seven tungsten-coated silicon vias and six connected gold arm patterns, which are fabricated using the TGSV technology. The electrical length of the proposed antenna is (3 λ o ×1.4 λ o). The designed antenna operates at the center frequency of 58 GHz. A prototype of the proposed antenna is fabricated by micromachining technology and tested. The simulated and measured results show that the proposed antenna has a wide operational bandwidth of 50.3 to 65 GHz for |S 11 | < −10 dB with a fractional bandwidth (FBW) of 25.5%. The measured peak gain is 6.3 dBi, and measured efficiency is 62% at the center frequency of 58 GHz. All measurements are in close agreement with simulated results. The proposed planar helical antenna with end-fire radiation is useful for applications in traveling-wave-tubes operating in millimeter-wave and higher frequencies, millimeter-wave on-board wireless communication, radar imaging, and tracking applications.

“…The use of highly directional antennas and their line-of-sight (LOS) propagation can effectively alleviate the signal interference in between the common channels to or from other systems [ 14 ]. To achieve this, high-gain directional antennas can be used at both the transmitting and receiving ends, resulting in a significantly enhanced SINR, a reduced Doppler effect, and improved data security, and can be used in long-range mm-wave point-to-point (P2P) communications with an LOS link [ 6 , 8 , 10 , 11 , 13 , 15 , 16 , 17 , 18 , 19 ]. The path loss can be reduced by using directional high-gain antennas [ 8 , 9 , 20 ].…”

Owing to the rapid growth in wireless data traffic, millimeter-wave (mm-wave) communications have shown tremendous promise and are considered an attractive technique in fifth-generation (5G) wireless communication systems. However, to design robust communication systems, it is important to understand the channel dynamics with respect to space and time at these frequencies. Millimeter-wave signals are highly susceptible to blocking, and they have communication limitations owing to their poor signal attenuation compared with microwave signals. Therefore, by employing highly directional antennas, co-channel interference to or from other systems can be alleviated using line-of-sight (LOS) propagation. Because of the ability to shape, switch, or scan the propagating beam, phased arrays play an important role in advanced wireless communication systems. Beam-switching, beam-scanning, and multibeam arrays can be realized at mm-wave frequencies using analog or digital system architectures. This review article presents state-of-the-art phased arrays for mm-wave mobile terminals (MSs) and base stations (BSs), with an emphasis on beamforming arrays. We also discuss challenges and strategies used to address unfavorable path loss and blockage issues related to mm-wave applications, which sets future directions.
