Abstract

A novel, very low profile, multi band and wide band monopole antenna for fifth generation wireless (5G) and Wireless LAN (WLAN) applications is proposed. The footprint of antenna is only 20mm x 15mm and is designed using economical FR-4 substrate of thickness 0.8mm. The compact structure of the proposed antenna composed of two "C-shaped" radiators pointing towards each other along with loading of circular radiator at each corner of C-shaped radiator and a rectangular tuning stub. The complete structure is fed by 50Ω microstrip line resulting in two resonances at 3.9GHz and 6.6GHz. The two resonances achieve 6 dB impedance bandwidth of 76% (3.30-7.35) GHz. The proposed antenna also exhibits a stable gain of around 2.25dBi, efficiency of around 85% and approximately omnidirectional radiation patterns in the functioning bands of interest. Therefore, because of good radiation characteristics, compact in size, and economical and simple in design, the proposed antenna is a good candidate for 5G and WLAN applications.

低轮廓，多波段和宽带“c形”单极天线，用于5G和WLAN应用

针对第五代无线(5G)和无线局域网(WLAN)的应用，提出了一种新颖的、非常低调的、多频带和宽带单极天线。天线的占地面积仅为20mm x 15mm，采用厚度为0.8mm的经济型FR-4基板设计。所述天线的紧凑结构由两个相互指向的“c”形散热器以及在c形散热器的每个角加载圆形散热器和矩形调谐短段组成。整个结构由50Ω微带线馈电，产生3.9GHz和6.6GHz两个谐振。这两种谐振实现了76% (3.30-7.35)GHz的6db阻抗带宽。该天线的稳定增益约为2.25dBi，效率约为85%，在感兴趣的功能频段内具有近似全向辐射方向图。因此，由于该天线具有良好的辐射特性，尺寸紧凑，设计经济简单，是5G和WLAN应用的理想候选者。
