EXPERIMENTAL CHARACTERIZATION OF A BROADBAND DUAL-POLARIZED MICROSTRIP ANTENNA FOR X-BAND SAR APPLICATIONS

摘要

The design and development of a broadband dual-polarized 16 × 16 element microstrip antenna array for X-band application is introduced. The measured bandwidth is about 17.8% for voltage standing wave ratios <1.5. The polarization isolation is better than 45 dB. The cross-polarization component is at the level of -37 dB below the main lobe.
