Abstract

WLAN is used for variety of applications. It has become the source of internet connectivity with a much higher data rates and is being successfully used at airports, university corridors, hotel lounges, hospitals, business centers and so on. Presently the most popular standards for WLAN being used are 802.11-b, g and n, in which standard “n” provides much higher data rate. For higher data rate, much higher bandwidth is needed. In this paper we have investigated the suitability of simple microstrip antennas i.e.(Bow-tie antenna, Elliptical inset-fed antenna and Rectangular inset-fed antenna) for WLAN applications, in comparison of more complex antennas. The purpose for choosing three different types of simple antenna structures is to analyze the reduced complexity of design with better performance amongst three. We have found that we can obtain considerable results even with the use of simple antenna structures in terms of bandwidth as compared to results obtained in previous studies. Analysis has been performed to find the relative gain, and impedance bandwidth of the three antennas.

用于WLAN应用的紧凑型天线的比较分析

WLAN用于各种应用。它以更高的数据速率成为互联网连接的来源，并成功地应用于机场、大学走廊、酒店休息室、医院、商务中心等。目前最流行的无线局域网使用标准是802.11-b、g和n，其中标准“n”提供更高的数据速率。为了获得更高的数据速率，需要更高的带宽。在本文中，我们研究了简单的微带天线，即(领结天线，椭圆插入馈电天线和矩形插入馈电天线)在WLAN应用中的适用性，并与更复杂的天线进行了比较。选择三种不同类型的简单天线结构，目的是分析在三种结构中，哪种结构的设计复杂度较低，性能较好。我们发现，与以往的研究结果相比，即使使用简单的天线结构，我们也可以在带宽方面获得可观的结果。分析了三种天线的相对增益和阻抗带宽。
