We introduce a defect-based horn antenna in a two-dimensional photonic crystal. Our numerical simulations demonstrate the efficient, highly directional nature of the antenna. It has a large operating bandwidth, low loss, and an operating frequency that is scalable to various regions of the electromagnetic spectrum. We also show that the photonic crystal horn antenna can be successfully used in an array configuration that uses a feed network made from photonic crystal waveguide circuits. The feed network and antennas have been integrated into a single photonic crystal device. This photonic crystal array antenna is shown to have high directivity and compact size while retaining the advantages of the photonic crystal horn antenna.
我们介绍了一种二维光子晶体中基于缺陷的喇叭天线。我们的数值模拟证明了该天线高效、高方向性的特性。它具有大的工作带宽、低损耗，并且工作频率可扩展到电磁频谱的各个区域。我们还表明，光子晶体喇叭天线可以成功地用于采用由光子晶体波导电路制成的馈电网络的阵列配置中。馈电网络和天线已集成到单个光子晶体器件中。这种光子晶体阵列天线被证明具有高方向性和紧凑尺寸，同时保留了光子晶体喇叭天线的优点。
