Abstract

Microstrip antennas have played an important role in the field of wireless communications in the past few decades. It is required in applications such as mobile handsets, PC cards or in PCS, miniaturized as well as wideband antennas. Engineers and researchers have made extensive efforts to miniaturize microstrip antennas, but small antennas inherently have narrow bandwidth. However, in order to transmit and receive more information, large bandwidths are required and bandwidth enhancement is currently a popular research. Some common broadbanding techniques are the use of multimode resonators, use of parasitic elements with main radiating patch and use of stacked patches [R. Garg et al., 2001]. All these techniques result in increasing the antenna size. Therefore, the issue of antenna miniaturization is of major interest [A.K. Skriverik et al., August 2001]. In [(S.K Sharma et al., June 2002) (S.K. Sharma et al.)], a monopole slot cut at one corner of the ground plane was presented with simulated and experimental results. In this paper, the monopole slot at the center of the ground plane is parametrically studied for its impedance bandwidth (S1/sub 1/= -10 dB) using method of moments (MOM) software Ensemble 8.0. The radiation characteristics are also investigated using finite element method (FEM) software, HFSS.

宽带微带单极槽天线

在过去的几十年里，微带天线在无线通信领域发挥了重要的作用。在移动电话、PC卡或PC机、小型化和宽带天线等应用中都需要它。工程师和研究人员已经为微带天线的小型化做出了大量的努力，但小型天线固有的带宽很窄。然而，为了传输和接收更多的信息，需要更大的带宽，带宽增强是目前研究的热点。一些常见的宽带技术是使用多模谐振器，使用带有主辐射贴片的寄生元件和使用堆叠贴片[R]。Garg等，2001]。所有这些技术都增加了天线的尺寸。因此，天线小型化的问题是主要的兴趣[A.K.]Skriverik等，August 2001]。在[(S。K Sharma et al.， 2002年6月)[S.K. Sharma et al.]，给出了在地平面一角切割单极子槽的模拟和实验结果。本文利用矩量法(MOM)软件对地平面中心单极槽的阻抗带宽(S1/sub 1/= -10 dB)进行了参数化研究。利用有限元软件HFSS对其辐射特性进行了研究。
