ABSTRACT This paper presents a novel high gain rectangular microstrip patch antenna (RMSA) with vertically placed Yagi elements. The antenna is fed by a coaxial probe to excite TM01 fundamental waves at 2.4GHz, which is suitable for wireless local area network (WLAN) applications. In order to increase the antenna gain, Yagi elements are placed in groups of 5, on each side of the substrate in order to serveas directors for the radiating slots as well as the ground reflections. The proposed antenna offers 1.3dB gain improvement and %3 .1 impedance bandwidth increase in comparison to the plain rectangular microstrip antenna with the same specifications. The advantage of this antenna is to provide an easy and cost effective solution to increase microstrip antenna gain, particularly in 8-10dB range, without disruptingits planar structure.

带有八木元件的高增益低剖面矩形微带贴片天线

摘要 本文提出了一种具有垂直放置的八木元件的新型高增益矩形微带贴片天线 (RMSA)。天线由同轴探头馈电以激发 2.4GHz 的 TM01 基波，适用于无线局域网 (WLAN) 应用。为了增加天线增益，八木元件以 5 个为一组放置在基板的每一侧，作为辐射缝隙和地面反射的导向器。与具有相同规格的普通矩形微带天线相比，建议的天线提供 1.3dB 增益改进和 %3 .1 阻抗带宽增加。这种天线的优点是提供一种简单且具有成本效益的解决方案来增加微带天线增益，特别是在 8-10dB 范围内，而不会破坏其平面结构。
