未来几代的无线系统预计将联合收割机与智能互联设备（物联网）结合使用高频波段（太赫兹范围）。为了实现这一雄心勃勃的合并，系统将需要可以安装在非平面物体上的天线，同时产生高度定向的波束。在这里，我们研究共形太赫兹漏波天线在太赫兹频率。我们发现了一组丰富的行为，可在太赫兹频率决定的几何参数和波长之间的相互作用。我们开发简单的模型来描述相关的物理，我们通过实验实现验证。我们还演示了使用共形太赫兹天线的数据传输，可以产生多个高增益波束，低误码率，增加太赫兹无线链路的覆盖范围。
Future generations of wireless systems are expected to combine the use of high-frequency bands (the terahertz range) with smart interconnected devices (the Internet of Things). To realize this ambitious merging, systems will require antennas that can be mounted on nonplanar objects while generating highly directional beams. Here, we study conformal THz leaky-wave antennas at THz frequencies. We find a rich set of behaviors accessible at THz frequencies dictated by the interplay among the geometrical parameters and the wavelength. We develop simple models to describe the relevant physics, which we verify by an experimental implementation. We also demonstrate data transmission using a conformal THz antenna that can generate multiple high-gain beams with low bit error rates for increased coverage of THz wireless links.
