中文摘要:
毫米波天线(一种传感器)未来将在移动通信、室内覆盖、雷达、定位等领域具备广泛应用前景,本文针对具有多向辐射特性的毫米波天线潜在应用,提出了一套(共四种)基于不同环形微带馈电方式、工作在60-GHz频段毫米波微带天线的新型设计思路。环形微带线作为馈电网络,将贴片单元连接起来,形成更紧凑的阵列结构。第一种结构是使用外环形微带线连接由1×3矩形贴片组成的四向线性阵列,从而获得8.4 dBi的增益和超过300 MHz的带宽;第二种结构是采用与上述相同贴片组成的两个线性阵列组成双向草叉形阵列,获得了9.85 dBi的增益和250 MHz左右的带宽;第三种结构是采用双(内外)环形微带馈线使上述四向线性阵列互相连接,而第四种结构使用桥式环形微带馈线。第三和第四种结构更接近实现多向辐射特性目标以及大于10 dBi的较高增益。

In this paper, a series of four novel microstrip antenna array designs based on different annular-microstrip feeding lines at 60-GHz millimeter wave (mmW) band are proposed, aiming at the potential usage of the mmW coverage antenna with multi-directional property. As the feeding network, the annular contour microstrip lines are employed to connect the patch units so as to form a more compact array. Our first design is to use an outer contour annular microstrip line to connect four-direction linear arrays composed of 1 × 3 rectangular patches, thus the gain of 8.4 dBi and bandwidth of over 300 MHz are obtained. Our second design is to apply the two-direction pitchfork-shaped array each made up of two same linear arrays as the above, therefore the gain of 9.65 dBi and bandwidth of around 250 MHz are achieved. Our third design is to employ dual (inner and outer contour) annular-microstrip feeding lines to interconnect the above four-direction linear arrays, while our fourth design is to bring bridged annular-microstrip feeding lines, both of which can realize the goal of multi-directional radiation characteristic and higher gain of over 10 dBi.
