摘要

本文提出了一种适用于三频(LTE/ GSM/ DCS/ PCS/ GPS)手机应用的小型频率可重构天线。天线被设计为在PIFA和LOOP模式下工作，这是通过控制PIN二极管的ON/ OFF状态来实现的。PIN二极管被放置在辐射臂的末端和接地面之间。仿真结果表明，PIFA模式下天线的6db反射系数带宽分别为36.65% (682 ~ 988 MHz)和20.60% (2286 ~ 2811 MHz)，环路模式下为27.82% (1504 ~ 1990 MHz)。通过选择不同模式之间的电气连接，单个天线可以有效地服务于各种通信系统。本文给出了反射系数和辐射方向图等天线特性。

Frequency reconfigurable triple wideband antenna for handheld device

This paper presents, a frequency reconfigurable antenna with compact size for triple wide-band (LTE/ GSM/ DCS/ PCS/ GPS) mobile phone applications. The antenna is designed to be operated in the PIFA as well as LOOP mode, which is achieved by controlling the PIN diode for its ON/ OFF states. The PIN diode is placed in between end of the radiating arm and ground plane. The simulated results show that the-6 dB reflection coefficient bandwidths of the proposed antenna are 36.65% (682-988 MHz) and 20.60% (2286-2811 MHz) in the PIFA mode and 27.82% (1504-1990 MHz) in the loop mode. Various communication systems are effectively served by a single antenna through selection of electrical connection between the different modes. In this paper, antenna characteristics like reflection coefficient and radiation patterns are presented.
