Characterization of miniature antenna for sub-GHz on-body applications

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 …

Realization of 3-D Flexible Antennas Using Liquid Metal and Additive Printing Technologies

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 …

Enabling Miniature Position Tracker Using LoRa and GPS Technology

Design of a miniature multi-band antenna system for positioning application is proposed in this paper. The effect of the battery and the casing is investigated. Simulated and measured results are presented. S-parameter and radiation results with a …

Investigation of hand effect on a handheld terminal at 11 GHz

In this paper, a 5G MIMO mobile phone prototype including four antennas working in the 10-13.2 GHz band is designed. The objective of the study is to evaluate the negative impact due to the user's hand in frequencies higher than 10 GHz. A 3D …

RSSI measurements to achieve mouse localization in a cage

The need in biological telemetry relevance has been growing steadily for many years. A localization system, working in the SRD (Short Range Devices) frequency band of 863870MHz dedicated to the laboratory mice, is presented in this paper. It is …
