In this paper, in order to solve the limitations of conventional technology schemes, a new scheme for large and medium‐sized frequency reconfigurable antenna array (FRAA) with low profile is proposed by combining advanced technologies such as new electromagnetic materials, reconfigurable antenna and integrated design. The proposed FRAA operating in X and Ku bands consists of a 4 × 4 antenna array, a w ide‐band feed network, a dual‐band electromagnetic band gap (EBG) plate and integrated bias network. The distance between antenna array and reflective plate has been reduced by 80.0% by applying an EBG structure. The influence of bias network on antenna performance is effectively reduced, and the performance of X/Ku two‐band antenna is ensured through the integrated optimization design of the bias network, EBG reflector plate and antenna array. Both simulation and test results show that the proposed FRAA has good performance.

大中型低剖面频率可重构天线阵列的集成设计

为了解决传统技术方案的局限性，结合新型电磁材料，可重构天线，集成天线等先进技术，提出了一种低剖面大中型频率可重构天线阵列（FRAA）的新方案。设计。提议的在X和Ku频段运行的FRAA由4×4天线阵列，宽带馈电网络，双频电磁带隙（EBG）平板和集成偏置网络组成。通过采用EBG结构，天线阵列和反射板之间的距离减少了80.0％。有效地降低了偏置网络对天线性能的影响，并通过偏置网络，EBG反射板和天线阵列的集成优化设计，确保了X / Ku两波段天线的性能。
