摘要

本文提出了一种适用于2.5/5.8 ghz无线局域网(WLAN)应用的带紧凑型辐射器的双频平面天线。天线由e形和t形辐射元件组成，产生两种谐振模式，实现双频工作。由50欧姆微带线直接馈电的t元件设计用于产生约5.5GHz的频段，以覆盖WLAN系统的两个更高频段(使用IEEE 802.11a标准)。e -单元通过t -单元耦合馈电，设计用于产生2.44GHz的频段，以覆盖WLAN系统的较低频段(使用802.11b/g标准)。因此，E-和t -元素合在一起非常紧凑，总面积仅为13.75*8.4mm2。利用ADS (ADVANCE DESIGN SYSTEM)进行了关键尺寸的参数化研究。天线设计为40*30*0.2mm3尺寸，采用FR4基板。测量了回波损耗、辐射方向图、增益和效率。

A novel dual-band E and T-shaped planar inverted antenna for WLAN applications

This paper presents a dual-band planar antenna with a compact radiator for 2.5/5.8-GHz wireless local area network (WLAN) applications. The antenna consists of an E-shaped and T-shaped radiating elements to generate two resonant modes for dual-band operation. The T-element fed directly by a 50 ohm micro strip line is designed to generate a frequency band at around 5.5GHz to cover the two higher bands of the WLAN system (using the IEEE 802.11a standard). The E-element is coupled-fed through the T-element and designed to generate a frequency band at 2.44GHz to cover the lower band of the WLAN system (using the 802.11b/g standards). As a result, the E- and T-elements together are very compact with a total area of only 13.75*8.4mm2. Parametric study on the key dimensions is investigated by computer simulation using ADS (ADVANCE DESIGN SYSTEM).The antenna is designed on a 40*30*0.2mm3 size with FR4 substrate. The stimulation results are measured for the return loss, radiation pattern, gain and efficiency.
