Abstract

This article discusses about device-to-device communication on 5G cellular networks using mmWave. Device-to-device communication will support 5G cellular technology, because it can be a solution to overcome the limitations of cellular coverage and service capacity. D2D can be used in a variety of applications. The main problem in D2D is that interference between signals in one cell will be very vulnerable to occur, so that effective resource management is needed. In addition, the use of D2D will also increase the complexity of a cellular system, in terms of resource management, interference, and also the routing required. Several studies have been carried out to create D2D communication that can be implemented effectively on 5G. One of them is research to perfect the load balancing scheme which is one of the functions obtained from D2D communication. Load balancing is the distribution of cellular traffic loads, using D2D the traffic load is channeled to communication between devices and reduces the burden on the main network.

Abstract

In the last decade, planar electromagnetic (EM) wave absorbers began to be widely studied. This type of EM wave absorber is thin, flexible, and easy to fabricate, which allows absorber to be used in new future applications. Split Ring Resonators (SRR) are one of many forms of absorber that is known to have an excellent absorbance performance. In this paper, square patch absorber, Axial Symmetric SRR (AS-SRR), and Axially Asymmetric SRR (AAS-SRR) are designed and observed in C-Band. From the simulation results, we obtained a square cell size of 30 mm, AS-SRR of 20 mm, and AAS-SRR of 18 mm. The three forms can reach absorption rates above 92%, with a bandwidth of 0.055 GHz, 0.076 GHz, and 0.081 GHz, respectively. Furthermore, the AAS-SRR design parameters were characterized, and the main parameters that influence the bandwidth and resonant frequency are the resonator length and resonator thickness. The maximum bandwidth of the characterization is 0.087 GHz.
