| Abstract: | A Ku-band dual-polarized and 4-element micro-patch array antenna is presented.The proposed antenna is analyzed by the simulator of IE3D.The measured results agree well with the simulated ones.The bandwidth at two ports is about 21.56% and 22.58%(for VSWR less than 2:1) respectively.The isolation between the two ports is better than 32dB across the entire operating bandwidth.The measured gain is about 12.8dBi. |
