太赫兹(THz)波在100 GHz到10 THz的频率范围内的应用引起了人们的广泛关注，特别是在宽带无线通信中。在太赫兹宽带无线设备中，利用InP衬底上的单载流子光电二极管(UTC-PD)进行光混频是一个关键问题，它被下转换成光信号到THz波。在这种情况下，太赫兹截面的损耗是一个严重的问题。因此，天线和过渡线应该制作在同一基板上。在我们以前的研究中，我们在InP衬底上设计了1×4和4×4平面阵列天线，采用单侧定向缝隙偶极子天线单元和分支共面波导(CPW)连接到UTC-PD的输出。本文介绍了一种用于300 GHz宽带通信的InP基片4×4相控阵天线。天线的总尺寸为1,930μm x 2,000μm x 18μm。4个1×4子阵天线平面堆叠，每个子阵天线通过共面波导连接到UTC-PD。每个天线单元布置在半个波长的距离上，以提高方向性。通过改变光纤上的延迟线，可以得到每个子阵的相位差。从每个天线单元之间的相位差来看，我们提出的相控阵天线具有波束锐利和波束定向的特点。
The terahertz (THz) wave applications at frequencies from 100 GHz to 10 THz has attracted much attention, especially in a broadband wireless communication. In the THz broadband wireless devices, photo mixing by using the unitraveling- carrier photodiode (UTC-PD) on the InP substrate is a critical issue, which is down-converted to the optical signal to THz wave. In this situation, the loss in the THz section is a serious problem. Therefore, antennas and transition lines should be fabricated on the same substrate. In our previous research, 1 x 4 and 4 x 4 planar array antennas using one-sided directional slot dipole antenna elements and branched coplanar waveguide (CPW) connected to the output of UTC-PD on the InP substrate is designed. In this paper, 4 x 4 phased array antenna on InP substrate for 300 GHz broadband telecommunication is demonstrated. The total antenna size is 1,930 μm x 2,000 μm x 18 μm. Four 1 x 4 subarray antenna are stacked planarly, and each subarray antenna is connected to the UTC-PD through the CPW. Each antenna element is arranged at the distance of half wavelength in order to sharpen the directivity. By changing the delay line attached to the optical fiber, the phase difference of each subarray can be obtained. From the phase difference between each antenna elements, our proposed phased array antenna has a sharp beam and beam steering characteristics.
