摘要
利用口径耦合馈电、双层微带贴片结构设计了一种用于Ku波段的宽带微带天线单元,并设计了64元宽频带高增益阵列天线。天线单元的仿真电压驻波比VSWR≤1.5的情况下,相对阻抗带宽达到25.6%。64元阵列天线的测量结果表明:相对阻抗带宽(VSWR≤1.5)达到8.9%,天线增益24.4dB,与仿真结果一致。
Aperture coupling feed and double-layer microstrip patch structure are applied to design broadband microstrip antenna unit and 64 elements high gain array antenna at Ku-Band. The simulate result of the unit shows that the relative bandwidth of VSWR ≤ 1.5 reaches 25.6%. From the measurement results of 64 elements array antenna: the relative impedance bandwidth (VSWR ≤ 1.5) reaches 8.9%, array antenna gain is about 24.4dB which agrees with the simulation .
