This article proposes a substrate integrated waveguide (SIW) antenna fed by microstrip transmission to operate in V‐band and fifth generation (5G) (60/70 GHz band) applications. The proposed millimeter wave (mm‐wave) antenna has an impedance bandwidth of 25.68 GHz (fractional bandwidth of 41%) between 49.77 and 75.45 GHz frequency and has a maximum realized gain of 3.75 dBi. Compared with other studies, the reported antenna has a size reduction of up to 73% with its 8 × 9.7 mm2 (1.33λ×1.61λ) dimension. The designed SIW patch is also fed by grounded coplanar waveguide transmission and its results are compared with the one fed by microstrip transmission line. Another important feature of the proposed antenna is that it has a low production cost, since it is printed on a cheap FR4 substrate material. Therefore, the proposed antenna has the potential to meet all the necessary requirements to be used for V‐band portable devices and applications. A 2 × 2 multiple‐input multiple‐output antenna based on the proposed antenna structure is also analyzed with respect to isolation, diversity gain and envelope correlation coefficient and acceptable results are obtained.

宽带低成本FR4环氧树脂基天线,带有H型槽,适用于V波段应用

本文提出了一种通过微带传输馈电的衬底集成波导(SIW)天线,可在V波段和第五代(5G)(60/70 GHz波段)应用中运行。拟议的毫米波(mm-wave)天线在49.77和75.45 GHz频率之间具有25.68 GHz的阻抗带宽(分数带宽为41%),最大实现增益为3.75 dBi。与其他研究相比,所报道的天线具有一个尺寸缩小的高达73%,其8×9.7毫米2(1.33 λ ×1.61 λ) 尺寸。设计的SIW贴片也通过接地共面波导传输馈电,其结果与微带传输线馈电的结果进行了比较。所提出的天线的另一个重要特征是生产成本低,因为它被印刷在便宜的FR4基板材料上。因此,建议的天线有可能满足用于V波段便携式设备和应用的所有必要要求。还针对隔离度,分集增益和包络相关系数对基于所提出的天线结构的2×2多输入多输出天线进行了分析,并获得了可接受的结果。
