Smartphones are affordable devices nowadays, capable of embedding a large variety of sensors such as magnetometers or orientation sensors, but also the hardware needed to connect them to most wireless communication technologies such as Wi-Fi, …
In this paper, a wearable waveguide surface for Body Area Network (BAN) communications is proposed. The designed structure is a via-less easy-to-manufacture waveguide surface optimized to work in the 2.6 GHz band. It is built on a flexible substrate, …
This paper presents simulation and measurement calculations of total scanning power and coverage efficiency parameters. The simulated and measured coverage efficiency Cumulative Distributive Function (CDF) are similar for high gain. Important …
In this work, we show how to set up a cellular LTE network for wireless experimentation and measurement, relying on commodity hardware and open-source software. We first deploy a complete LTE network on a single laptop and an SDR hardware. Then, we …
In this letter, an integrated frequency-tunable inverted-F antenna is presented. Thanks to a reconfigurable circuit using a digitally tunable capacitor (DTC), the antenna resonant frequency can be shifted over 32 different positions from 600 to 960 …
This paper presents the experimental evaluation of the effects of the user's fingers on the performance of a 5G terminal antenna array operating in the European 5G regulated band at 26 GHz. Matching and radiation characteristics of a four-element …
This paper presents a multiband MIMO antenna system with four accesses, with very good performance despite the complex environment that surrounds it. This environment consists of a thick plastic radome protecting the antenna and an aluminum metallic …
In this paper, the effect of the human body proximity on LPWAN antennas is investigated. Both numerical and experimental tests are performed on two different IoT devices. The obtained results show that the performance degradation caused by the body …
In this paper, a fast characterization technique for on-body small devices is presented. This method is used to extract the radiation performance of two different structures placed on a belt over a human abdomen at 868 MHz. Results show that the …
This paper presents a low-cost measurement method for MIMO antenna performance assessment based on the open-source OpenAirInterface initiative. MISO 8×1 measurements are presented to experimentally prove the reproductibility of the test method, using …
