| 摘 要： | An 8×1-element wideband dual-polarized slot-coupled microstrip antenna array with high isolation and low cross-polarization in X-band is presented. The array antenna offers an impedance bandwidth (VSWR≤2) of 23% and 21% for dual polarization ports, respectively. The measured isolation between two polarization ports is better than 35 dB and the measured cross-polarization level below -25 dB in the main beam over the operation frequency band of 9.35 GHz to 9.75 GHz. This array is well suitable for X-band SAR (synthetic aperture radar) antenna application.

| Abstract: | An 8 × 1-element wideband dual-polarized slot-coupled microstrip antenna array with high isolation and low cross-polarization
in X-band is presented. The array antenna offers an impedance bandwidth (VSWR≤2) of 23% and 21% for dual polarization ports,
respectively. The measured isolation between two polarization ports is better than 35 dB and the measured cross-polarization
level below −25 dB in the main beam over the operation frequency band of 9.35 GHz to 9.75 Ghz. This array is well suitable
for X-band SAR (synthetic aperture radar) antenna application.
