Abstract

This paper describes design procedure of a high-performance miniaturized antenna with an array configuration, which contributes to enhancing the communication system’s performance. The basic antenna features a compact size (6 x 6) mm2, and its single element is an H-shaped slotted patch printed on the top side of a Rogers RT5880 substrate, with a relative permittivity and thickness of 2.2 and 0.3 mm, respectively. The edge-to-edge distance of the 2 × 1 array antenna is 9 x 14 mm2, and the isolation between its radiation elements is 4.5 mm. To increase the capabilities of the antenna in terms of gain and bandwidth, we proceeded to use the 2 × 1 array configuration and then optimized the model via either the width of the feed line or the elliptical edges of the patch. The miniaturized array antenna achieved a peak gain of 12.56 dB, a directivity of 13.11 dBi, and a return loss of -47.52 dB at a resonance frequency of 91.5 GHz, with a radiation efficiency of more than 91% over an operating bandwidth of 15.83 GHz, ranging from 79.7 GHz to 95.6 GHz. The design and simulation results of the proposed antenna were obtained using the CST Studio software.

一种用于毫米波应用的新型高效高增益超宽带开槽H形印刷2×1阵列天线的设计，通过馈线和椭圆边缘提高带宽和增益

本文介绍了一种具有阵列结构的高性能小型化天线的设计过程，它有助于提高通信系统的性能。基本天线具有紧凑的尺寸(6 x 6) mm2，其单个元件是印刷在Rogers RT5880衬底顶部的h形槽贴片，相对介电常数和厚度分别为2.2和0.3 mm。2 × 1阵列天线的边到边距离为9 × 14mm2，其辐射元件之间的隔离度为4.5 mm。为了提高天线在增益和带宽方面的能力，我们继续使用2 × 1阵列配置，然后通过馈线的宽度或贴片的椭圆边缘来优化模型。小型化阵列天线在91.5 GHz谐振频率下的峰值增益为12.56 dB，指向性为13.11 dBi，回波损耗为-47.52 dB，在79.7 GHz ~ 95.6 GHz 15.83 GHz工作带宽范围内的辐射效率超过91%。利用CST Studio软件对天线进行了设计和仿真。
