“…Figures 4(b), 4(c), and 4(d) present the power splitters designed to steer the beam at 15, 30, and 45 °, respectively. These splitters are being used only for characterization of the array, as the plan is to integrate this array with 16-path RFIC [11].…”

“…The results presented in this paper are limited to 0, 15, 30, and 45 °as only four different power splitters are fabricated to characterize the performance of the array. However, this array shall be integrated with the 16-path 57-71 GHz beam-forming Si-Ge transceiver chip [11] which can excite each feed point of CSAA with appropriate phase and amplitude to steer the beam at any arbitrary angle in ± 45 °and beyond.…”

“…The 3 dB beam-steering range is at least ± 45 °as higher angles are not tested. The proposed solution is planned to be integrated with 16-path RFIC [11] that can steer the beam at any arbitrary angle in the beamsteering range. Besides, this paper is an extension of the research presented in [12].…”

This paper presents a 60 GHz connected slots linear-phased array feeding a high-gain semi-symmetric lens antenna. This design provides high gain, broadband, and beam-steering capabilities for gigabit rate access and backhaul communications. The connected slots antenna array (CSAA) is excited at 16× equidistant points which not only yields spatial power combining but also allows the progressive phase changes to steer the beam in ±45° in azimuth plane. To characterize the CSAA-fed lens antenna, four different power splitters are fabricated which steer the main beam in 0, 15, 30, and 45°. The lens is designed in a way to overcome the scan loss and get comparatively higher gain when beam is steered away from the broadside. The measured results show 25.4 dBi maximum gain with 3 dB gain bandwidth covering the full band 57–66 GHz whereas 3 dB beam-steering range is ±45° for all frequencies. Besides, the half power beamwidth is 6 and 10° in elevation (E-plane) and azimuth plane (H-plane), respectively.

“…5G networks will revolutionise the existing communications supporting the increasing capacity demands of the huge amount of end-users (UEs) within small cells while guaranteeing connections with low latency and high quality of service (QoS) [1]. These novel systems will operate in the lightly licensed or unlicensed millimetre wave (mm-wave) bands (e.g., segment of V-band: 57-71 GHz) [2]. The beneficial aspect of operating in an unlicensed band resides on the nonexisting channel segmentation allowing carrier aggregation of the whole bandwidth for point-to-point (P2P) links.…”
