Abstract

Antenna plays a major role in communication irrespective of wired or wireless. Design of a compact antenna is a challenge in current scenario as the field grows drastically. In this paper, we have studied and analyzed the polygonal structure for the antenna structure and are used for array design. Four different geometrical shapes are considered in this work where the centre patch is a square one with dimension of 11X11mm. The array of 3X3 and 4X4shape with four different shapes are analyzed. It is observed from simulation results that hexagonal shape out performs other shapes both in 3X3 array structure and 4X4 array structure in terms of gain, return loss and bandwidth. The study suggests for Ku band application and its further study for Ku band range expansion as it is obtained for 15.75GHz with bandwidth of 1.5GHz and 8.04dBi gain.
阵列天线增益改进分析
无论有线还是无线,天线在通信中都起着重要的作用。随着无线通信领域的迅猛发展,小型化天线的设计成为当前的一大挑战。本文对天线结构中的多边形结构进行了研究和分析,并将其用于阵列设计。在这个作品中考虑了四种不同的几何形状,其中中心补丁是一个尺寸为11X11mm的正方形。分析了4种不同形状的3X3和4x4形状阵列。仿真结果表明,在3X3阵列结构和4X4阵列结构中,六角形结构在增益、回波损耗和带宽方面都优于其他形状。研究建议Ku波段应用,并进一步研究Ku波段扩展,因为它在15.75GHz带宽为1.5GHz,增益为8.04dBi。
