The design of a novel 1×16 dual-polarized linear microstrip antenna array is introduced.The element is the dual-polarized corner-fed square patch

while the vertical polarization port of the array is fed with a coplanar feed

and its horizontal polarization port is fed with the aperture-coupled feed.In addition

the pair-wise anti-phase feeding technique is used in both feed networks.The experimental results show that the bandwidths of VSWR＜1.5 reach 15% and 13.5% for the two ports

respectively

and the isolation between the dual polarized ports is better than 33dB within the operating bandwidth

whose maximum reaches 43dB.This linear array can be used as a sub-array of spaceborne synthetic aperture radar (SAR) system by connecting it with the active transmitter/receiver (T/R) components.
