“…To enhance the RF to DC conversion efficiency, a fully differential topology is preferred. Dipole and yagi uda antennas can be used for differential configuration 9,10 but due to less gain and large size, efficiency of the harvesting system suffers. Differential configurations can also be realized using Wilkinson power divider to drive a full‐wave rectifier 11 or utilizing FR4 substrate 12 for rectification circuits.…”

This paper presents three configurations of broadband differentially fed microstrip antenna for GSM1800, 1900 and 2100 MHz. The antennas are designed and fabricated using two different substrates for bottom and upper layer. The three antennas designed and tested have gain of 9.88, 9.66, and 11.14 dBi, respectively, at the center frequency. The proposed antennas also find its implementation in areas where, differential inputs/outputs wireless communication circuits are needed. Later, a differentially driven RF power harvesting system with maximum efficiency of 71%, 67% and 78% for a load of 520 Ω is also designed and developed.
