研究目的
To develop a high-gain wide-bandwidth antenna array capable of providing 1800 coverage and utilizing minimum space in the mobile phone for 5G smartphone applications.
研究成果
The proposed 16-element antenna array integrates broadside and end-fire antennas to achieve 1800 coverage with wide bandwidth and high gain, making it suitable for 5G smartphone applications. It outperforms existing designs in terms of bandwidth, coverage, array size, and ease of fabrication.
研究不足
The antenna array has not been fabricated or measured; only simulation results are presented. Future work includes fabrication and experimental validation.
1：Experimental Design and Method Selection:
The study involves designing a phased array antenna with 16 elements (8 dual-polarized patch antennas and 8 modified Yagi-Uda antennas) arranged alternately at the bottom edge of a smartphone chassis. Simulations are used to evaluate performance.
2：Sample Selection and Data Sources:
The design is based on a standard 5-inch smartphone size (130 mm × 74 mm ground plane) with a PCB size of 150 mm × 74 mm using Rogers RT5880 Duroid substrate.
3：List of Experimental Equipment and Materials:
Rogers RT5880 Duroid substrate (dielectric constant 2.2, loss tangent 0.009), SMPM connectors for feeding, and simulation tools for analysis.
4：2, loss tangent 009), SMPM connectors for feeding, and simulation tools for analysis.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The antenna elements are designed and simulated for reflection coefficient, isolation, and radiation patterns. The array is configured with specific element separations to minimize grating lobes and ensure good isolation.
5：Data Analysis Methods:
Simulation results are analyzed for bandwidth, gain, isolation, and radiation patterns using standard antenna performance metrics.
