위성 SAR용 광대역 이중편파 적층형 패치 배열 안테나 설계 및 제작 = Design and Fabrication of A Wide-Band Dual-Polarization Stacked Patch Array Antenna for Satellite SAR Applications

다국어 초록 (Multilingual Abstract)

This paper proposes a wide-band dual-polarization stacked patch array antenna for satellite SAR system applications. The array antenna was designed for loss minimization and wide-band characteristics to enhance the performance of the SAR system and optimize it for active return loss in applications to active phased arrays. The fabricated array antenna showed a performance of 19.26%/19.79% fractional bandwidth within the -10 dB reference level of the active return loss and showed loss characteristics of 0.797 dB/0.799 dB averaged within the operational frequency for both H/V-polarization cases. The pattern performance was verified by comparing the measured patterns with the calculated patterns obtained by the array factor.
