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 …
The uniplanar compact photonic bandgap (UC-PBG) metamaterial structure has been profitably used for antenna miniaturization and radiation enhancement purposes. This paper presents an additional way to exploit it, when it is employed as ground plane …
