Millimeter wave (mmWave) is an interesting research area in recent years. Transition connectors are key components of mmWave passive systems. The commercially available cable connectors are lossy and expensive in mmWave frequencies. In this paper, various ...
The transformation of the automotive industry towards ubiquitous connection of vehicles with all kind of external agents (V2X) motivates the use of a wide range of frequencies for several applications. Millimeter-wave (mmWave) connectivity represents a par ...
In this paper, a dual-polarized four-port 2 × 2 series fed antenna array operating at 28 GHz with beam-switching capability is proposed. The antenna array uses a simple passive beamforming network to switch the main beam. The presented antenna design is su ...
Deployable emergency communication systems are a backbone solution for replacing damaged network infrastructures and/or providing high-end services in case of an emergency event. It is important that such systems are up-to-date with the latest mobile netwo ...
Millimeter wave (mmWave) frequencies has become a research area of interest in recent years because of providing broad available bandwidth and thus higher data rates. Wideband mmWave antenna is one of the important development areas in wireless communicati ...
This paper discusses the design, fabrication, and measurement of a two-layer, 2×10 elliptic, microstrip series fed antenna array operating at 28 GHz for 5G and mm-wave user equipment. A branch line coupler was used as a feeding network that can generate th ...
This paper presents a low-cost, compact, multibeam planar antenna system with a wide ±138∘ beam coverage angle at 28 GHz for 5G applications. The proposed microstrip based design includes two branch-line couplers and a Butler matrix with 2×10 and 4×10 seri ...
In this study, one method of using antennas based on fractals to cover few kinds of public protection and disaster relief (PPDR) communications was presented. Dedicated antenna forms, necessary for antenna design by 5G implementation, were enhanced to suit ...
Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time and frequency domains. For engineering time-modulated systems, one needs to th ...
Today, a large portion of mobile data traffic is consumed behind the shielding walls of buildings or in the Faraday cage of trains. This renders cellular network coverage from outdoor cell sites difficult. Indoor small cells and distributed antennas along ...
