Abstract

This paper presents the design of two multiband millimetre wave antennas for wireless communications. The design is performed using Computer Simulation Technology (CST) Microwave Studio tool. The performance of the antennas is evaluated in terms of gain, radiation efficiency and scattering parameter. The first one is a quad band antenna having a size of 5.2 mm by 5.5 mm and resonance frequencies at 35.68 GHz, 45.20 GHz, 55.42 GHz and 80.55 GHz. At the largest frequency of 80.55 GHz, the bandwidth, the gain and the directivity of this antenna are 3.5 GHz, 5.9662 dB and 6.353 dB, respectively. The second antenna is the array form of the first antenna. This penta band array antenna has resonance at 34.77 GHz, 47.23 GHz, 58.43 GHz, 69.63 GHz and 80.55 GHz. At the largest frequency of 80.55 GHz, the array antenna has a bandwidth, gain and directivity of 2.31 GHz, 13.792 dB and 15.14 dB, respectively. However, the array antenna has a larger size than the single antenna being 12.4 mm by 6.5 mm. Compared with the existing 80 GHz antennas, the proposed single and array antennas have compact size.

用于无线通信的两种紧凑型多波段毫米波天线

本文设计了两种多波段毫米波无线通信天线。该设计是使用计算机仿真技术(CST)微波工作室工具进行的。从增益、辐射效率和散射参数三个方面对天线的性能进行了评价。第一种是四波段天线，尺寸为5.2 mm × 5.5 mm，谐振频率为35.68 GHz、45.20 GHz、55.42 GHz和80.55 GHz。在最大频率为80.55 GHz时，该天线的带宽为3.5 GHz，增益为5.9662 dB，指向性为6.353 dB。第二天线是第一天线的阵列形式。该五波段阵列天线的谐振频率分别为34.77 GHz、47.23 GHz、58.43 GHz、69.63 GHz和80.55 GHz。在最大频率为80.55 GHz时，阵列天线的带宽为2.31 GHz，增益为13.792 dB，指向性为15.14 dB。但是，阵列天线的尺寸比单个天线大，为12.4 mm × 6.5 mm。与现有的80ghz天线相比，本文提出的单天线和阵列天线具有体积小的特点。
