5G Mobile Communications

The development of 5G (fifth generation) mobile communication systems was initiated to meet the expected need for higher data rates. In this article, a new 28/38 GHz dual-band “inverted-F” array antenna for 5G applications is proposed. This antenna can be integrated in OLEDs (Organic Light Emitting Diodes) panels which can be used both for lighting or display. This 5G antenna, composed of 32 elements, has the advantage of a dual-band and compact structure. Each element of the array antenna has the shape of an “inverted-F” antenna. This array antenna can cover the 28 GHz band (27.94–28.83 GHz) and the 38 GHz band (37.97–38.96 GHz) with mutual coupling between the elements less than −35 dB. The characteristics of the end fire radiation beams were obtained by employing an array of 32 “inverted-F” antenna elements on the upper and lower portions of the PCB (Printed Circuit Board). The suggested design has a gain of approximately 16.52 dB at 28.38 GHz and 15.35 dB at 38.49 GHz, which is suitable for 5G mobile communications.

The Fifth-Generation (5G) mobile communications system is now on its way to being deployed worldwide and the scale of 5G subscribers in some region has reached a very large scale. However, the attention of academia and industry is increasingly shifting towards the next generation technology called Sixth Generation (6G) and many pioneering works are being kicked off by the major players in this filed, placing an important milestone in the history of mobile communications. At this juncture, a view of the current state of the art of 6G research and a vision of future communications are of great interest. This paper thus aims to investigate up-to-date 6G research programs, activities, and main viewpoints of representative countries, institutions and companies worldwide. Then, the key technologies are outlined and a vision on ``What 6G may look like?" is provided. This paper aims to serve as an enlightening guideline for interested researchers to quickly get an overview when kicking off their 6G research.

5G Mobile Communications

The design of compact dual band grid array antenna (GAA) designed on FR-4 substrate for future Fifth Generation (5G) Mobile Communications at 10 GHz is reported. The proposed antenna uses coaxial technique of feeding and has a dimension of 48 mm × 55 mm × 1.6 mm. Simulation results using CST microwave studio illustrates that the antenna has a band from 10.03 GHz to 10.68 GHz and another band from 10.7 GHz to 12.23 GHz. This excludes the 10.68 – 10.7 GHz band in which emissions were forbidden by the Radio Regulations in the sense that it has been allocated for the Radio Astronomy, Space Research and Earth Exploration Satellite (passive). The antenna has a maximum gain of 8.03 dBi at 10 GHz, thus a good candidate for the future 5G mobile communications.

In this proposed paper, a single band microstrip patch antenna for fifth generation (5G) wireless application was presented. 28, 38, 60 and 73 GHz frequency bands have been allocated for 5G mobile communications by International Telecommunications Union (ITU). In this paper, we proposed an antenna, which is suitable for the millimeter wave frequency. The single band antenna consists of new slot loaded on the radiating patch with the 50 ohms microstrip line feeding used. This single band antenna was simulated on a FR4 dielectric substrate have relative permittivity 4.4, loss tangent 0.02, and height 1.6 mm. The antenna was simulated by Electromagnetic simulation, computer software technology High Frequency Structural Simulator. And simulated result on return loss, VSWR, radiation pattern and 3D gain was presented. The parameters of the results well coherent and proved the literature for millimeter wave 5G wireless application at 38 GHz.
