摘要：Jute textile is made from natural fibres and is known for its strength and durability. To determine if jute could be used as a substrate for microstrip antennas, its electromagnetic characteristics (permittivity and loss tangent) are measured in the band of 1 GHz to 5 GHz. The obtained data are used to compare the performances of a simple rectangular patch antenna resonating at 2.45 GHz on jute with others using different textiles as a substrate. Comparing the simulation results gives an idea of using jute as a substrate for microstrip antennas. In the second part of this paper, a truncated patch antenna on jute is studied to be used for wireless power transmission at 2.45 GHz. The antenna was simulated and then fabricated. The measured reflection shows a shift in the resonance frequency compared to the simulated one. The frequency shift is explained, and a solution is proposed to correct it; a second antenna was fabricated and measured.
