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 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 presents a very low consuming re-configurable antenna suitable for ultra-low power internet-of-things (IoT) devices. Thanks to the use of a Digital Tunable Capacitor (DTC), the antenna can be reconfigured to obtain good impedance matching …
This letter presents a reconfigurable antenna for mobile terminals with extended band coverage obtained by using a digitally tunable capacitor (DTC). The antenna structure is matched permanently over high frequency bands including DCS/PCS, UMTS, LTE …
Internet of thing will soon connect billion of objects together. Interference with existing standard in the ISM bands and outside is a hot issue to solve. Ultra-narrow band modulation has recently been proposed to decrease interference for low-data …
This paper presents an approach for the synthesis of pattern-reconfigurable antenna suitable for integration into smart wireless sensor nodes. As a proof-of-concept, a simple antenna configuration capable of steering the radiation main beam towards …
