摘要

本文提出了一种圆极化方槽天线的新设计。该天线为单层结构，l型短节分别加载在天线的两个相对角上，能够产生用于圆极化激励的正交模式。所建议的天线的顶部和左侧部分的两个非对称带和各种其他非对称带也被加载。拟议的结构尺寸为40 x 40 x 1.6 mm3。设计的CPSSA工作在3.2-12.5 GHz范围内，AR带宽在4.5-8.5 GHz范围内。本文详细阐述了不对称存根的加入对系统的增益增益和回波损耗(S11)等性能参数的改善。

A CPW-Fed Square Slot Circularly Polarized Antenna With Asymetrie Stubs For Ultra Wideband Applications

This paper presents a new design for a Circularly Polarized Square Slot Antenna (CPSSA). The proposed antenna is single layered with L-shaped stubs loaded on both the opposite corners of the antenna, which is capable of generating orthogonal modes for the excitation of Circular Polarization. Two asymmetric strips on the top and the left portions of the proposed antenna and various other asymmetric strips are also loaded. The proposed structure is having the dimensions of 40 x 40 x 1.6 mm3.The designed CPSSA operates in the range of 3.2-12.5 GHz with Axial Ratio (AR) bandwidth in the range of 4.5-8.5 GHz. In this paper the improvement of the performance parameters like AR and Return Loss (S11) on the addition of asymmetric stubs is explained in detail.
