“…Additional dielectric plates Some authors take the view, that mutual coupling between elements in TSA arrays has positive effect because it allows to significantly decrease lower operation frequency [5]. But such effects, in author's opinion, makes individual TSA array element directional pattern behavior difficult to predict because of frequency depending phase of adjacent element re radiated power.…”

This paper presents a design of concave spherical base Vivaldi feed array for beam steering without the use of any phase shifters. The research goal is reached through the use of Luneberg lens aperture and switching of active feed array element.Vivaldi array element has solid metal sheet design with stripline feeding for linear polarization. Special elements are used for mutual coupling effects weakening and directional pattern back lobe suppression at low frequencies.The design has such advantages, like broad bandwidth, wide scan angle in azimuth and elevation, low loss level, and machining simplicity of feed array.

“…Many papers were dedicated to coupling interaction between elements of an antenna array [1][2][3]. Calculation of the far-field radiated by an antenna array excited with a time-harmonic signal taking into account coupling between elements of the array can be based on introducing equivalent impedances for corresponding interactions.…”

“…The antennas show good radiation patterns as well as good gain flatness except in the IEEE 802.11a frequency band [14]. Another kind of radiating element considered suitable for phased arrays is the class of Vivaldi antennas, also known as quasi-end-fire nonresonant radiator or tapered slot antennas (TSAs) [15]. However, the element is normally fabricated by cutting a notch in a metal plate and backed by a quarter-wave cavity behind the feed point to improve its forward gain.…”

“…Numerous microstrip UWB antenna designs have been proposed [10][11][12][13][14][15]. For instance, a patch antenna has been designed as a rectangular radiator with two steps, a single slot on the patch, and a partial ground plane etched on the opposite side of the dielectric substrate.…”

The cloud radio access network (C-RAN) is one of the most efficient, low-cost, and energy-efficient radio access techniques proposed as a potential candidate for the implementation of next-generation (NGN) mobile base stations (BSs). A high-performance C-RAN requires an exceptional broadband radio frequency (RF) front end that cannot be guaranteed without remarkable antenna elements. In response, we present state-of-theart antenna elements that are potential candidates for the implementation of the C-RAN's RF front end. We present an overview of C-RAN technology and different types of planar antennas operating at the future proposed fifth-generation (5G) bands that may include the following: (i) ultra-wide band (UWB) (3-12 GHz), (ii) 28/38 GHz, and (iii) 60-GHz radio. Further, we propose different planar antennas suitable for the implementation of C-RAN systems. We design, simulate, and optimize the proposed antennas according to the desired specifications covering the required frequency bands. The key design parameters are calculated, analyzed, and discussed. In our research work, the proposed antennas are lightweight, low-cost, and easy to integrate with other microwave and millimeter-wave (MMW) circuits. We also consider different implementation strategies that can be helpful in the execution of large-scale multiple-input multiple-output (MIMO) networks.
