“…The equal impedance matching is necessary to achieve the real-to-real impedance matching between a resistive transmitter/receiver and a resistive power line characteristic impedance to minimize the signal reflection [62,64]. The complex conjugate matching is done to achieve the real-to-complex impedance matching between a resistive transmitter/receiver and a complex PLC network access impedance to maximize signal power transfer [69][70][71]. The voltage maximization matching is operated at R s = 0 and X s = −X i to achieve complex-to-complex impedance matching between a complex transmitter and a complex load to improve the SNR [59].…”

Impedance mismatch that degrades signal power transfer and affects communication reliability is a major obstacle for power line communications (PLC). Impedance matching techniques can be designed to effectively compensate for the impedance mismatch between PLC modems and power line networks at a specific frequency or for a given frequency band. In this paper, we discuss the tradeoffs that need to be made when designing an effective impedance matching network. We also make a comprehensive review of previous state-of-the-art PLC impedance matching techniques and provide a useful classification of each technique. Finally, we discuss important issues (concerns) and provide suggestions for research directions deserving more attention. This review provides a useful guideline for researchers and manufacturers to quickly understand impedance matching principles and facilitate the design of an effective impedance matching coupler for PLC applications.

The advent of power line communication (PLC) for smart grids, vehicular communications, internet of things and data network access has recently gained ample interest in industry and academia. Due to the characteristics of electric power grids and regulatory constraints, the effectiveness of coupling between the power line and PLC transceivers has become a very important issue. Coupling devices used to inject or extract data communication signals into or from power lines are very important components of a PLC system. There is, however, an obvious gap in the literature for a detailed review of existing PLC couplers. In this paper, we present a comprehensive review of couplers, which are required for narrowband and broadband PLC transceivers. Prevailing issues that protract the design of couplers and consequently subtended the inventions of different types of couplers are clearly described. We also provide a useful classification of PLC couplers based on the type of physical couplings, voltage levels, frequency bandwidth, propagation modes and a number of connections. This survey will guide researchers, as well as designers alike, into a quicker resourcing when studying coupling in narrowband and broadband PLC systems.

“…However, traditional monopole [1] and dipole antennas are narrow band antennas by nature, and they only offer bandwidths of the order of 5% to 10% at their centre frequencies. Using an efficient wideband matching network [2][3][4][5][6] the narrow band antenna can be converted to a wideband antenna. For this to happen, the main parameters such as antenna input impedance (Z a ), characteristic impedance (Z 0 ), matching network impedance (Z m ), reflection coefficient (Γ) and the voltage standing wave ratio (VSWR) should be characterised.…”

This paper presents the design of a wideband blade shaped monopole antenna with a horizontally mounted aluminium tube on top of the blade covering 135-175 MHz frequency band using Electromagnetic Simulation software (CST Microwave Studio TM) along with a matching network whose characteristics have been evaluated by the Optimal Matching Network Identifier (OMNI) algorithm. OMNI algorithm is a search technique used in computing, to find the optimum solution. The conventional quarter wavelength monopole antenna is a narrow band antenna with bandwidth of the order of 5% to 10% at its centre frequency. In order to increase the bandwidth of the antenna, a proper matching network has been incorporated along with it. Toroidal inductor based matching networks have been designed, and their characteristics are evaluated using Optimal Matching Network Identifier (OMNI) program in MATLAB software. By consolidating MATLAB and CST simulated results, the antenna prototype along with the optimal matching network has been practically implemented, and corresponding results have been verified. The details of simulated and measured results are also included. The proposed antenna finds numerous applications in various wideband communication systems.
