Abstract

Satellite communication systems for mounting on vehicles are commonly based on phased array antennas with electronical beam steering. In this work we develop active metasurface-based receive-transmit antenna arrays for newly deployed satellite constellation system running in Ku-band. Both receive and transmit subarrays are based on patch-antenna elements driven in circular polarization using 90 hybrids. In both subarrays we optimized elements sizes and array period to have optimal ellipticity, gain, side lobe level. In electromagnetic simulations we achieved realized gain of 32.2 dBi for the Rx subarray and 33.4 dBi for the Tx subarray obtained in a broad scanning angle range from − 15 to + 45.

卫星通信ku波段相控阵天线工作研究
用于安装在车辆上的卫星通信系统通常基于带有电子波束转向的相控阵天线。在这项工作中,我们为新部署的ku波段卫星星座系统开发了基于主动超表面的收发天线阵列。接收和发射子阵都是基于贴片天线元件,在圆偏振下使用90°混合天线驱动。在这两个子阵列中,我们优化了元件尺寸和阵列周期,以获得最佳的椭圆度、增益和旁瓣电平。在电磁模拟中,我们在-15°到+45°的宽扫描角范围内实现了Rx子阵的32.2 dBi和Tx子阵的33.4 dBi增益。

期刊介绍: This journal establishes a dedicated channel for physicists, material scientists, chemists, engineers and computer scientists who are interested in photonics and nanostructures, and especially in research related to photonic crystals, photonic band gaps and metamaterials. The Journal sheds light on the latest developments in this growing field of science that will see the emergence of faster telecommunications and ultimately computers that use light instead of electrons to connect components.
