A Miniaturized Dual-Band Meander Line Antenna for RF Energy Harvesting Applications

A dual band electrically small meander line antenna is designed for RF energy harvesting applications. The antenna is designed to cover the most known wireless cellular networks such as GSM 900, GSM 1800 and UMTS. The dual band property is achieved by using two different radiators, each of them is responsible for covering one band and a lambda/4 transformer is used to match the antenna at 915 MHz. The antenna is fabricated on Rogers RO4350 board and the measured results had a good agreement with simulated ones. The fabricated antenna is compared to a reference antenna (a dipole antenna). Both antennas are tested with an RF energy harvesting kit and the maximum covered distance is recorded. The total size of the proposed antenna was 45 x 32.6 x 1.52 mm(3).
