“…The reference paper [8] was the only one that has been considered irregular reflector surfaces for mmWaves. The paper [8] refers to a flat reflector with wedges that emulates a parabolic reflector with a fixed focal position, that can be used for satellite communications , because it reduces its volume . So our goal is to adapt this idea to design a diffuse reflector according to our research.…”

In future implementations of 5G systems , it is essential the use of the spectrum in the range of mm-Waves frequencies , in order to offer to the users the bandwidth proposed in the standard. However , using this frequency range lead to many technical difficulties in which the most important challenge is the critical attenuation of the signal in non-line-ofsight (NLOS) environments in indoor environments. Therefore is essential to plan strategies that allow us to mitigate the problem of signal attenuation in this kind of complex environments and ensure the viability of using this technology in short term. Then the objective of this research is the design of a passive reflector that allow us to redirect the energy of the transmitting antenna efficiently in order to avoid the obstacles of the environment , and therefore avoid excessive losses .

The need for communication amongst people and electrical systems motivated the emergence of a large number of telecommunications protocols. The advances in digital networks and the internet have contributed to the evolution of telecommunications worldwide. The purpose of this chapter is to provide students and researchers with a clear presentation of telecommunications core protocols that are utilised in different research domains including telephony, brain-computer interface (BCI) and voice and digital telecommunications. Indeed, BCI involves different electrical signals, communications concepts and telecommunications protocols. This chapter introduces the reader to the core concepts in communications including analogue and digital telecommunications protocols that are utilised generally in communications and in particular in BCI systems. The topics covered in this chapter include telecommunications protocols, communications media, electrical signals, analogue and digital modulation techniques in digital communications, softwaredefined radio, overview on 10-Mbps Ethernet protocol and Session Initiation Protocol (SIP).

Parabolic reflectors have very good directivity. However, when put behind a partially reflecting surface, they suffer from destructing in‐phase rays and they experience deteriorated characteristics. In this work we consider fixing this impediment and we enhance the low profile by providing a new approach based on ray optics model. This approach grabs the equations of multiple reflections between the two components to re‐construct a collimated beam in the normal direction of the radiated element. This model is confirmed with a peak simulated directivity of about 28 dB of the new compact parabolic quasi Fabry–Pérot cavity. The highly directive and low profile proposed model is valid for both microwave and mmWave bands (from 5 to 60 GHz). The measured realized gain of the fabricated prototype is compared with a simulated data resulting in a peak of about 25.2 dB.
