摘要

本文提出了一种便于无线通信应用中双频工作的印刷贴片天线。该天线的工作频率为2.45 GHz和3.48 GHz，适用于蓝牙2.0和Wi-MAX等无线通信应用。采用低损耗阻燃剂-4设计了相对介电常数εr = 4.4，介电损耗正切为0.02的天线。所设计的多频段频率天线尺寸为70 × 60 × 2.87 mm3。同轴馈电被用作所提出的矩形贴片天线的馈电。对于2.45 GHz和3.48 GHz的工作频率，观察到相应的7.69 dB和5.78 dB的可观增益。天线的几何形状由两个对称的方形槽组成，这些槽与提供双频操作的辐射贴片中心的交叉槽等距放置。

Slotted Planar Dual-band Antenna for Wireless Communication

A printed patch antenna that facilitates dual-band frequency operation for wireless communication applications has been presented in this paper. The presented antenna facilitates operation at the frequencies of 2.45 GHz and 3.48 GHz which are useful in wireless communication applications such as Bluetooth 2.0 and Wi-MAX. A low loss Fire Retardant-4 has been used to design the antenna having relative permittivity εr = 4.4 and dielectric loss tangent of 0.02. The presented multi-band frequency antenna has dimensions of 70 × 60 × 2.87 mm3. The coaxial feed has been used as feed to the proposed rectangular patch antenna. A considerable gain of 7.69 dB and 5.78 dB for the operating frequencies of 2.45 GHz and 3.48 GHz accordingly is observed. The geometrical shape of the antenna consists of two symmetrical square slots placed equidistant from a cross-slot in the center of the radiating patch which provides the dual-band operation.
