摘要

本文提出了用于移动通信应用的双频平面倒F天线(PIFA)的新概念。通过在PIFA主辐射贴片下引入矩形寄生元件来设计双频天线，从而实现双频工作频率。这种双频PIFA可以在两个不同的工作频率下工作，即2600兆赫用于长时间演进(LTE)频段7和3500兆赫用于WiMAX应用。天线由位于阻燃剂4 (FR4)介电基片上方的矩形平面元件和在顶部辐射贴片与地平面之间连接的短板组成。所述接平面沿所述基板的底边定位。该天线外形尺寸为17.8 mm × 16.5 mm，天线高度为5mm。在两种不同的工作频率下，天线的增益为4 ~ 5dbi，模拟的辐射方向图几乎是全向的。本文从天线结构、回波损耗、远场辐射方向图、驻波比和天线增益等方面介绍了天线的设计。

Dual-band Planar Inverted F Antenna with parasitic element for LTE and WiMAX mobile communication

In this paper, a new conception of dual-band Planar Inverted F Antenna (PIFA) for mobile communication application purposes have been staged. The dual- band antenna is designed by introducing a rectangular form of parasitic element which is located under the main radiating patch of the PIFA in order to attain a dual-band operating frequencies. This dual-band PIFA can be operated at two different operating frequencies which are 2600 MHz for Long Tem Evolution (LTE) Band 7and 3500 MHz for WiMAX application. The antenna is made up from rectangular planar element located above the Flame Retardant 4 (FR4) dielectric substrate and the shorting plate that connect between the top radiating patch to the ground plane. The ground plane is positioned along the bottom side of the substrate. The overall dimension of this antenna is 17.8 mm × 16.5 mm and the height of the antenna is 5 mm. The simulated radiation pattern shows nearly omni-directional with obtaining a gain antenna of 4 to 5 dBi at two different operating frequencies. The antenna design in term of antenna structure, return loss, far field radiation pattern,VSWR and antenna gain are presented in this paper.
