Abstract

A compact reconfigurable four bands Planar Inverted-F Antenna (PIFA) is presented for Digital Video Broadcasting — Handheld (DVB-H), Universal Mobile Telecommunications System (UMTS), Global System for Mobile Communications (GSM800, 900, 1800 and 1900), Personal Communications System (PCS), Wireless Local Area Network and Bluetooth (WLAN), Worldwide Interoperability for Microwave Access (m-WiMAX) and Hiperlan/2 applications. Two varactor diodes with variable capacitors are used to electrically tune the operating frequencies over a wide range. The overall size of the radiated parts is 31.5 × 30.5 mm2 which makes it easy to integrate it into small mobile handset. Depending on the voltage applied to the switches the operating frequencies at 0.7 GHz, 2 GHz, 3.5 GHz and 5 GHz can be tuned over 30.48%, 20%, 4% and 4% respectively. The peak gains for the four bands range −4dBi, 3dBi, 3dBi and 6dBi at DVB-H, UMTS, WiAMX and WLAN, respectively. The average efficiency of the four bands ranges from 95% to 85%. The radiation patterns and other discussions are provided.

无线应用中基于PIFA的可重构多波段天线

一种紧凑型可重构四波段平面倒f天线(PIFA)，用于手持式数字视频广播(DVB-H)、通用移动通信系统(UMTS)、全球移动通信系统(GSM800、900、1800和1900)、个人通信系统(PCS)、无线局域网和蓝牙(WLAN)、微波接入全球互操作性(m-WiMAX)和Hiperlan/2应用。两个可变电容的变容二极管用于在很宽的范围内电调谐工作频率。辐射部件的整体尺寸为31.5 × 30.5 mm2，便于集成到小型手机中。根据施加在开关上的电压，0.7 GHz、2 GHz、3.5 GHz和5 GHz的工作频率可以分别调到30.48%、20%、4%和4%以上。在DVB-H、UMTS、WiAMX和WLAN四个频段的峰值增益分别为- 4dBi、3dBi、3dBi和6dBi。四个波段的平均效率在95% ~ 85%之间。给出了辐射图和其他讨论。
