“…Then, a low-profile antenna solution with beam-steering capabilities is proposed in in (Hong et al 2014). A Vivaldi phased antenna array performance and it's user effects are investigated in (Ojaroudiparchin et al 2015). In (Hussain et al 2017) a compact 4G MIMO antenna is integrated with the 5G mm-wave mobile array.…”

In this paper, a dual-band dual-polarized phased antenna array for 5G mobile terminals is proposed. The array has a bandwidth of 3.6 GHz and two resonances at 30.5 and 32.8 GHz. The array has a clearance of 2.85 mm and fed with two ports in simulation to excite the notch and dipole parts of the proposed antenna structure. Finally, the proposed antenna element is combined into two arrays with different configurations. It is shown that it is better to use the array of 8 elements than to use two 4-element sub-arrays with orthogonal orientation.

“…Vivaldi antennas were employed on either side of the link because they offer wide bandwidth as well as good directional features which have the potential to be suitable for mmWave 5G communications [13]. The Vivaldi antenna is fed using a microstrip line on the rear of the board which excites the tapered slot.…”

Abstract-A 5G millimeter-wave radio over fibre optical fronthaul system based on optical heterodyning, utilising an externally injected gain switched distributed feedback laser, is successfully demonstrated. Five bands of UF-OFDM are transmitted over 25 km of fibre and a 28 GHz Vivaldi Antenna wireless link. Transmission performance below the 7% FEC limit is achieved with an aggregate total data rate of 4.56 Gb/s.

“…The much higher gain that is needed to compensate the higher signal attenuation at mmWave introduces the concept of antenna arrays for cellular phones [3]. But the use of antenna arrays to increase the antenna gain causes the antenna radiation pattern to be directional thus requiring the use of beam steering on the antenna [4] [5].…”

It will be diffcult to use either omnidirectional or fixed beam antenna due to the high propagation losses caused by atmospheric absorption at mmWave for 5G mobile communication. Several studies have been conducted recently using butler matrix which is part of switchable antenna with some advantages such as simple, minimal cost, low loss, etc. Previous studies also have designed vivaldi array antenna at 28 GHz which provides a fix beam directional radiation pattern with narrow beam that requires real phase setting. However, there has been no research using vivaldi antenna with butler matrix, whereas it has some advantages such as wide bandwidth, high gain, high directivity, etc. This paper proposed 4x4 butler matrix integrated with vivaldi antenna by using phase shift of 45 . The design is developed on a single layer of Rogers RT5880 with dielectric constant 2.2 and thickness 0.254 mm. Best results of simulation were picked for overall system at 28 GHz, and the results of antenna as follows: the return loss was below -10 dB, the realized antennas gain was 10.2 dB with unidirectional radiation pattern and bandwidth antenna of 6 GHz that covers from 25 GHz to 31 GHz. The butler matrix average phase di erent between output port are -44.106 o , 137.38 o , -137.66 o , 43.95 o with phase error of 0.894 o , 2.38 o , 2.66 o , 1.06 o .Antenna array that has been given di erent phase by butler matrix is able to shift radiation pattern on the input port successively with range of beam that can be achieved equal to 185 o .
