A compact pattern reconfigurable antenna with four radiation patterns is proposed for sub-GHz IoT applications. The antenna has two functional modes; Mode I has three uncorrelated patterns, while Mode II has electric and magnetic omnidirectional …
In this paper, an electronically pattern reconfigurable antenna for Internet of Things (IoT) applications is presented. The antenna consists of 4 wire-patches sharing the same ground plane. This radiating element can switch between four end-fire …
This paper presents an approach based on Machine Learning (ML) to estimate the performance of small antennas in practical applications. As a proof of concept, the case of printed antennas integrated into compact terminals, such as for Internet of …
This work presents the design of a NB-IoT integrated antenna for LTE band 20 on a compact 50x30 mm terminal. The study will start from the Q factor limitation analysis and finish with a simulated prototype considering the different techniques to …
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 …
In this paper, a slot-based electronically steerable parasitic array radiator (ESPAR) antenna suitable for Internetof-Things (IoT) applications is proposed. The antenna can provide 12 directive and 2 slightly different omnidirectional radiation …
A miniature antenna working in European, Asian and Australian ISM sub-GHz bands is presented for IoT application. The antenna was first designed and simulated to achieve a low quality factor, i.e. having good matching at 896MHz. A second-order …
A pattern agile antenna for smart IoT gateways operating at 2.44 GHz is presented. Several radiation patterns pointing in different directions and characterized by different beamwidths can be obtained.
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 …
