“…The inherent flexibility in the overall lens manufacturing opens new possibilities for, e.g., ultra-compact mm-wave front-ends with fully integrated beam-scanning capabilities [33] providing smart user tracking in future mobile WLAN/WPAN communication and localization systems. Surprisingly, even the planar lens itself may become an attractive degree of freedom in advanced (and highly tailored) antenna system design [29] where multiple objectives are usually at stake, for example in advanced (cognitive) MIMO systems where bandwidth, angular/spatial diversity and far-field gain are all subject to optimization.…”

Abstract-A broadband gradient index (GRIN) metamaterial lens for gain enhancement of circularly polarized antennas has been automatically designed, fabricated and investigated. The GRIN metamaterial lens consists of an isotropic dielectric plate with a corresponding distribution of deep-subwavelength drill holes each with the same diameter. Such drill holes have a negligible influence on both the polarization state and the spectral response of the electromagnetic wave transmitting through the resulting GRIN metamaterial lens. Therefore, the GRIN metamaterial lens is polarization-insensitive and can efficiently transform spherical waves into planar waves over a very broad frequency range keeping the initial polarization states (e.g., linear or circular) scarcely changed. In the following we have derived analytical formulas that enable the setup of distribution rules

“…12, it consists of a dielectric lens of an elliptical or quasi elliptical shape integrated with a set of driven elements. The elements of the array are offset by a specific distance, d, from each other and mounted at the back focal plane of the lens [33,36,[47][48][49][50][51]. The lens is placed in a way that the radiation from each element appears to emanate from the same focal point and the elements are controlled by means of a switch, activating each element one at a time to implement the different predefined angles of steering [47,50].…”

“…The insertion losses associated with each switch were 2.5 dB. In [50], the ILA was extended to accomplish 2D steering by using a 2 dimensional 8 element array operating at 77 GHz. Scan angles of 17 • and 25 • were reported with gain of 16 dBi for 15 mm lens radius.…”

“…The gain achieved is the combined gain of a single element and the lens. This ILA concept was improved in [50] by adding elements in two dimensions to accommodate steering in two planes but the two dimension improvement still had the limitation of one active element at a time. Also, it only offers predefined steering angles which implies that the connection will be lost if the receiving antenna is displaced from its predefined position.…”

Pattern reconfigurable antennas (beam steerable antennas) are essential for various applications in electronic engineering such as telecommunication and radar. They mitigate interference by channelling the antenna's radiation to the direction of interest. This ability is vital for millimetre wave frequency applications such as small cell backhaul links where high path loss, attenuation from obstacles, and misalignment due to wind sway and accidents are prevalent. Several techniques have been used to implement beam steering over the years, most of which achieves steering at the expense of antenna performance. In this article, we surveyed the various techniques used in achieving beam steering and analyse each based on some figures of merit with the aim of identifying areas of improvements for each beam steering technique.

“…As an alternative to beamforming antennas, beam steering lens antennas could also be used [39][40][41][42]. These antennas would also have an array of antenna elements, but only one of them is selected for transmission/reception depending on the desired direction.…”

User level performance analysis of multi-hop in-band backhaul for 5G

In recent years, mobile access networks operating at millimeter wavelengths have received a great deal of attention, as they promise previously unattainably high mobile data rates. At these frequencies, mobile access links are expected to use highly directional beamforming antennas, which are also well suited to backhaul links. Therefore, access points can efficiently act as self-backhauled relays by using the same spectrum, circuits and antennas for mobile access and backhaul links, thus forming a multi-hop in-band backhaul network. The contributions of our paper are extensive simulations to investigate user level performance in such multi-hop networks. We specifically take into account the momentary data traffic of every link in order to calculate the interference. Results quantify the detrimental effect of interference on user level performance. Furthermore, the potential benefit of using the combination of in-band and dedicated backhaul links is evaluated. Additionally, this paper investigates the user level effects of the sudden loss of a link in the backhaul mesh network, and underlines the importance of effective rerouting algorithms. The feasibility of the inband concept is demonstrated, and we can confirm that the user level experience will surpass the performance provided by previous generation mobile networks.
