摘要

─本文介绍了一种用于5G应用的四频带频率可调天线，该天线工作在低于6 GHz的频率范围内。在顶部，在廉价的玻璃环氧基板上印刷一个填塞的方形贴片，在另一侧，在部分接平面上嵌入一个c形槽。为了实现具有一致辐射方向图的频率可重构性，使用了c形槽和匹配短段。该天线通过在c形槽中放置两个正固有负二极管(PIN)和在存根和馈线之间放置一个PIN二极管来实现电子频率可调。该频率可根据PIN二极管的开关条件在一个超宽带(UWB)和三个通信频段之间进行调谐。所提出的配置很小，衬底尺寸为25×25×1 mm。对天线进行了制作和测试，得到了与仿真结果相吻合的测量结果;它可以在超宽带(3.31.0-6.03 GHz)和三种通信模式(3.31-4.32、3.784.98、4.98-5.96 GHz)之间切换。该天线在四个频段的峰值增益分别为1.91、1.86、2.0和2.0 dB，辐射效率分别为80、78、83和86%。开发的天线非常适合多功能无线系统和认知无线电应用，因为它覆盖了6ghz以下的频段，并且在宽窄频带之间可调。索引术语─窄带，PIN二极管，四波段，可重构，方形贴片，存根，可调谐，超宽带。

Sub-6 GHz Quad-Band Reconfigurable Antenna for 5G Cognitive Radio Applications

─ This article describes a quad-band frequency tunable antenna for 5G applications that operates in the sub-6 GHz frequency range. On the top side, a stubloaded square patch is printed on an inexpensive glass epoxy substrate, and on the opposite side, a C-shaped slot embedded into the partial ground plane. To achieve frequency reconfigurability with a consistent radiation pattern, the C-shaped slot and matching stub are used. The antenna is electronically frequency tunable by placing two positive intrinsic negative diodes (PIN) in the C-shaped slot and one PIN diode between the stub and feed line. The frequency is tunable between one ultra-wideband (UWB) and three communication bands based on the switching conditions of the PIN diodes. The proposed configuration is small, with a substrate dimension of 25×25×1 mm. The antenna was fabricated, tested and found measurements result back up the simulation; it can switch between UWB (3.31.0-6.03 GHz) and three communication modes (3.31-4.32, 3.784.98, 4.98-5.96 GHz). The antenna has peak gains of 1.91, 1.86, 2.0 and 2.0 dB, and radiation efficiencies of 80, 78, 83 and 86%, respectively, in the four frequency bands. The developed antenna is ideally suited for multi-functional wireless systems and cognitive radio applications since it covers the frequency bands below 6 GHz and is tunable between wide and narrow bands. Index Terms ─ Narrow band, PIN diode, quad-band, reconfigurable, square patch, stub, tunable, ultra wide band.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
