Abstract

The Radial Line Slot Array (RLSA) antenna is known for its good characteristics such as low profile, low cost, aesthetically pleasing, ease of installation and simple structure. This research involves the optimization of the design and development of a novel linearly polarized Beam Squinted Radial Line Slot Array (RLSA) antenna at 5.8 GHz band. The research objective is to study the optimum size of the antenna that can give an acceptable antenna's performance. There are four prototypes with different sizes has been developed and the measurements were obtain a return loss at 17.12 dB, antenna gain of 21 dB and 18.80% antenna bandwidth with 63.10% radiation efficiency for 400 mm diameter antenna design.

5.8 GHz波束斜视径向线槽阵列天线的优化设计
径向线槽阵列(RLSA)天线以其外形小、成本低、美观、安装方便、结构简单等特点而闻名。本文研究了一种新型的线极化波束斜视径向线槽阵列(RLSA)天线在5.8 GHz频段的优化设计与开发。研究的目的是研究天线的最佳尺寸,使天线的性能达到可接受的水平。研制了4个不同尺寸的样机,测量结果表明,400 mm直径天线的回波损耗为17.12 dB,天线增益为21 dB,天线带宽为18.80%,辐射效率为63.10%。
