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 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 miniature antenna in Ultra High Frequency (UHF) band fabricated using liquid metal and additive technologies. Such an approach allows the accurate realization of compact and complex antenna structures. The design as well as the …
In certain communication applications it is advantageous to constrain the shape of the far-field, as to make it act as a spatial filter. This can mitigate interference from other antennas. Such constraints on the far-field behavior, in particular for …
In this paper, a reconfigurable antenna integrated into a miniature device for asset tracking is presented. This antenna system has the ability to compensate environment effect by tuning the antenna resonance frequency. The proposed solution is …
In this work, we compare two different antenna topologies integrated in a miniature IoT device working at 900 MHz: Inverted F Antenna (IFA) and Dielectric Resonator Antenna (DRA). This type of handheld device can be strongly impacted by human body …
This letter proposes an approach for the realization of three-dimensional flexible antennas based on the use of liquid metal and additive printing technologies. As a representative example, a miniaturized inverted-F antenna (IFA) operating at 885 MHz …
This paper presents a method to design 3D flexible antennas using liquid metal and additive technology (3D printer based on Fused Deposition Modeling (FDM) technology). The fabricated antennas present flexible properties. The design method is first …
