Abstract

Nowadays, the generalization of wireless communication systems and the need to miniaturize antennas to allow their integration into small objects at ultra-high frequencies is growing. At these frequencies, the antenna is the bulkiest component and its miniaturization constitutes one of the most important current challenges for designers of communicating objects. The main objective of our work is the design of a dual-band patch antenna working for fifth-generation systems. For this purpose, we designed a miniature antenna having two resonance frequencies, one around 7GHz and the other around 28GHz. For this, our work is based on a classic rectangular patch antenna. Miniaturization techniques and ground plane deformation (GDS) are used to obtain the best performance. A parametric study was performed to see the most influential parameters to achieve the desired requirements. The influence of the geometrical parameters of the antenna on the resonance frequency, bandwidth, and directivity has been taken into consideration. The results obtained showed a good performance of the designed antenna.

5G应用非对称馈线微型双波段贴片天线设计

如今，无线通信系统的推广和小型化天线的需求正在增长，以使其能够在超高频下集成到小型物体中。在这些频率下，天线是体积最大的部件，其小型化构成了通信对象设计者当前最重要的挑战之一。我们工作的主要目标是设计一个适用于第五代系统的双频贴片天线。为此，我们设计了一个具有两个共振频率的微型天线，一个在7GHz左右，另一个在28GHz左右。为此，我们的工作是基于经典的矩形贴片天线。采用小型化技术和地平面变形(GDS)来获得最佳性能。进行了参数研究，以了解最具影响力的参数，以达到所需的要求。考虑了天线几何参数对谐振频率、带宽和指向性的影响。实验结果表明，所设计的天线具有良好的性能。
