Broadband differential antenna for full-wave RF energy scavenging system

This research work demonstrated in this paper is part of a larger project that aims to design high efficiency miniaturized RF energy scavenging system. In this paper, a broadband differential antenna is designed for a full-wave RF energy scavenging system. Simulation results demonstrate that the proposed antenna shows a wide bandwidth of 3.48 GHz based on S parameters <; -10 dB, covering most of the wireless communication bands which include GPS (L1: 1575.42 MHz, L2: 1227.60 MHz, L3: 1381.05 MHz, L4: 1379.913 MHz, L5: 1176.45 MHz), DCS (1710-1880 MHz), PCS (1850-1990 MHz), UMTS (1920-2170 MHz), WiFi/WLAN/Hiper LAN/IEEE 802.11 2.4 GHz (2412-2484 MHz), 3.6 GHz (3657.5-3690.0 MHz), Bluetooth (2400-2484 MHz), WiMAX 2.3 GHz (2.3-2.5 GHz), 2.5 GHz (2500-2690 MHz). 3.3 GHz and 3.5 GHz (3400-3600 MHz) & LTE applications.
