摘　　要：为满足高集成度有源相控阵天线对低剖面瓦片天线的需求,设计了一种Ka波段双极化微带天线。并且为该天线设计一种6dB幅度加权的不等功分馈电网络,采用“T”型共面耦合的馈电方式,使得天线在谐振频率获得较好的阻抗匹配,极化隔离度和交叉极化均优于-30 dB。具有剖面地、重量轻等特点,且大幅降低了Ka波段天线的加工难度,有较强的工程应用价值。A Ka band dual polarization microstrip antenna was designed to meet the requirements of high integration active phased array antennas for low profile tile antennas.And design a 6dB amplitude weighted unequal power division feeding network for the antenna,using a T-shaped coplanar coupling feeding method,to achieve good impedance matching at resonant frequency,with polarization isolation and cross polarization better than-30dB.It has the characteristics of profile,light weight,and significantly reduces the processing difficulty of Ka band antennas,making it highly valuable for engineering applications.
