Abstract
This paper explores the influence of metamaterial structures on the performance of LTE/Wi-Fi printed antennas, examining two antenna versions. One version integrates a metamaterial ground layer, representing the traditional antenna, while the other incorporates a metamaterial load attached to the modified antenna. The inclusion of the metamaterial ground layer supports the unit cell with the MTM structure, enabling an analysis of how the MTM structure impacts antenna performance. Testing is conducted using Roger 5880 substrate with a thickness of 1.575 mm and a dielectric constant of 2.2. The antenna's overall dimensions are 60×49×1.575mm, with a loss tangent of 0.0009. Once optimal inductor/capacitor values are determined, equivalent circuits are generated for both the planned and conventional circuits. These circuits are simulated using CST Microwave Studio, with the Path Wave ADS simulator running the equivalent circuit. Antenna manufacturing and measurement are conducted using a Network Analyzer. Frequency ranges covered by the antenna include 1.68 GHz to 2.51 GHz, 3.56 GHz to 4.63 GHz, and 4.1 GHz to 5.1 GHz, suitable for standard applications. Simulated gain is reported as 2.58 dB/2.45 dB, with observed gain at 2.22 dB/5.19 dB, showing excellent agreement between measured and simulated values from both simulators. Additionally, simulated specific absorption rate (SAR) on a sample Breast Phantom ensures compliance with the 1g/10g SAR value requirements set by the European Union and the United States. This confirms the antenna's suitability for cancer diagnosis and detection applications.
