Abstract

This paper presents the development of aperture-coupled patch antennas operating in industrial scientific and medical band at 60 GHz (57 GHZ to 64 GHz), with square and circular shapes, for on-chip application. The aperture-coupled antenna proposed is composed by a transmission feed line, an aperture and patch element built in aluminum with 10 micrometers of thickness lying on two layers of silicon with height of 200 micrometers. Dimensions of the square and circular antennas were calculated according to the effective wavelength for resonance frequency at 60 GHz in order to match at 50 Ohms. The proposed antennas have been simulated using the commercial software ANSYS. Both antennas show omnidirectional radiation pattern, with half power beamwidth greater than 149 degrees. Square patch presented a more compact structure, with dimension less than 1.55 mm, return loss of −55 dB, and bandwidth of 3.98 GHz, however the circular antenna, with a greater metallic area, achieved a better gain of 5.88 dBi.

用于ISM频段60ghz的孔耦合片上贴片天线

本文介绍了在60 GHz (57 GHz至64 GHz)工业科学和医疗频段工作的孔耦合贴片天线的发展，具有方形和圆形，用于片上应用。所提出的孔径耦合天线由传输馈线、孔径和贴片元件组成，贴片元件采用厚度为10微米的铝制成，置于两层高度为200微米的硅上。根据60 GHz谐振频率下的有效波长计算方形和圆形天线的尺寸，以匹配50欧姆的谐振频率。利用商业软件ANSYS对所设计的天线进行了仿真。两天线均呈全向辐射，半功率波束宽度大于149度。方形贴片结构更紧凑，尺寸小于1.55 mm，回波损耗为- 55 dB，带宽为3.98 GHz，而圆形天线的金属面积更大，增益为5.88 dBi。
