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 reconfigurable patch antenna design operating at 868MHz for Low Power Wide Area Network (LoRa), 1.58 GHz for Global Positioning System (GPS) and 2.4 GHz for Bluetooth is presented. The design is reconfigurable thanks to the …
This paper deals with the design of antennas enabling miniature and energy efficient wireless internet-of-things (IoT) devices for smart cities. Because of the characteristics required by IoT systems, some specific aspects must be considered during …
This paper addresses the design and measurement of an implantable RFID tag for small animal monitoring applications. In particular, the design of a miniature printed dipole antenna and its integration with a commercial RFID transceiver is discussed. …
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 …
This paper presents a compact low-profile surface wave antenna for UMTS applications. It shows good impedance match and dipole-like omnidirectional radiation pattern over the band of interest. Numerical and experimental results are reported to …
In this letter, an antenna operating over the GSM band is proposed. Thanks to the use of a foam material as dielectric substrate, the prototype of this antenna is particularly light. It has a very low profile with overall dimensions equal to 0.31λ × …
