Abstract

Patch antennas are highly used in the last few years in domains like spaceships, satellites and missiles, cellular phones, radars, GSM, wide area computer networks and also wireless local areas. This is the result of their advantages, namely the small dimensions and weight, their low cost, ease of use, ease of integration in other circuits and capability to operate at 2 or 3 frequency values. Their disadvantages, among which low efficiency, high quality factor and a narrow bandwidth must be improved. In order to do so, we must previously study the influence of different parameters on their functioning. In this paper, three different feeding types will be implemented on patch antennas and the resulting parameters will be compared and analyzed. Also, different operating frequencies will be taken into account in order to determine the dimensions of such an antenna. Considering the Rogers RT Duroid 5880 dielectric and its standard thicknesses patch antennas will also be modeled and parameters like S parameters, the bandwidth, directivity, gain will be analyzed.

贴片天线馈电对其参数的影响

在过去的几年里，贴片天线在宇宙飞船、卫星和导弹、移动电话、雷达、GSM、广域计算机网络和无线局域网等领域得到了广泛的应用。这是它们的优点的结果，即小尺寸和重量，低成本，易于使用，易于集成在其他电路中，并且能够在2或3个频率值下工作。它们的缺点是效率低、质量因数高、带宽窄，必须加以改进。为了做到这一点，我们必须事先研究不同参数对其功能的影响。本文将在贴片天线上实现三种不同的馈电方式，并对产生的参数进行比较和分析。此外，为了确定这种天线的尺寸，将考虑到不同的工作频率。考虑到Rogers RT Duroid 5880电介质及其标准厚度贴片天线也将建模，并对S参数等参数进行带宽、指向性、增益等分析。
