摘　　要：微带天线阵列以其重量轻,体积小,成本低等优点在无线通信中有着广泛应用。提出了一种低损耗,高效率馈电网络的设计方法,并利用该馈电网络设计并加工了一个32单元Ku频段矩形贴片微带天线阵列,在中心频率处实现了23.36dBi的天线增益和80.6%的口径效率,显示了极高的工程实用价值。Microstrip antenna array is intensively utilized in wireless communication because of light weight, small size and low cost. A new feed network design with little loss and high efficiency is introduced in this paper, and a high-performance Ku-band antenna with 32 elements is designed accordingly. The measured peak gain at centre frequency reaches 23.36 dBi with an aperture efficiency of 80.6%, demonstrating high practical value in engineering.
