Abstract

In this paper, a novel V-shaped slotted single, dual band frequency reconfigurable antenna is presented for upcoming 5G and C-band applications. The antenna operates around 3.9 GHz (5G), around 5.5 GHz Wireless Local Area Networks (WLAN) and 6.37 GHz for C-band applications. For obtaining the reconfigurability in the designed structure a V-shaped slot is etched on hexagonal shape radiating element and a PIN diode is adopted. If the PIN diode is ON state, the proposed radiating structure provides dual band operations in the frequency range of 3.49-4.46 GHz with centre frequency around 3.9 GHz and 5.59-7.59 GHz with centre frequency around 6.37 GHz with a bandwidth of 970 MHz, 2000 MHz respectively, else provides a single band operation in the frequency range of 4.03-7.14 GHz with centre frequency around 5.5 GHz with bandwidth of 3110 MHz. A hexagonal shape radiating patch element is incorporated on FR-4 substrate with overall size of (30 x 28 x 1.6) mm3. A comparative analysis with cutting edge work demonstrates that the presented designed antenna structure has the advantages of compact size, improved bandwidth and gain.

一种新型的v形开槽单、双频可重构天线，适用于c波段/ 5G应用

本文提出了一种新型的v形开槽单、双频可重构天线，用于即将到来的5G和c波段应用。该天线工作在3.9 GHz (5G)、5.5 GHz无线局域网(WLAN)和6.37 GHz的c波段应用。为了获得设计结构的可重构性，在六角形辐射元件上刻蚀v形槽，并采用PIN二极管。当PIN二极管处于ON状态时，所提出的辐射结构在3.49-4.46 GHz频率范围内提供中心频率约为3.9 GHz的双频工作，在5.59-7.59 GHz频率范围内提供中心频率约为6.37 GHz的双频工作，带宽分别为970 MHz、2000 MHz，否则在4.03-7.14 GHz频率范围内提供中心频率约为5.5 GHz的单频工作，带宽为3110 MHz。在FR-4基板上集成了六角形辐射贴片元件，其总体尺寸为(30 x 28 x 1.6) mm3。与前沿工作的对比分析表明，所设计的天线结构具有体积小、带宽和增益提高等优点。
