摘要

研究了一种具有缺陷地面结构的多波段平面倒f天线用于无线移动通信。所提出的天线采用倒f结构配置，并采用传输线馈电技术进行激励。仿真结果表明，地平面上的槽具有双重功能:在低频时对地平面谐振进行调谐，在高频时充当寄生辐射体。利用该技术的优势，开发了在1.2 GHz、3.1 GHz和5.2 GHz谐振的天线模块。该天线在各谐振频率下阻抗匹配均在< -10 dB。该天线在介电常数为4.4、厚度为1.66 mm、损耗正切为0.02的FR - 4衬底上实现。利用IE3D电磁求解器对天线结构进行了仿真分析。

Multiband PIFA Antenna for Narrow-band and Wideband Wireless Application

A multiband planar Inverted-F antenna with defected ground structure is investigated for wireless mobile communication. The proposed antenna is configured using a Inverted-F structure and excited using transmission line feeding technique. It is demonstrated by the aid of simulation that the slots on the ground plane have dual function:to tune the ground plane resonance at low frequency and to act as parasitic radiators at high frequencies. Taking the advantages of this technique, an antenna module is developed resonates at 1.2 GHz, 3.1 GHz and 5.2 GHz. The proposed antenna shows better impedance matching of < –10 dB at each resonant frequency. The antenna was realized on FR 4 substrate with dielectric constant of 4.4, thickness of 1.66 mm and loss tangent of 0.02. The antenna structure is simulated and analyzed using IE3D EM solver.
