A Conformal Phased Array with Low Profile and Wide-Scanning Performance for SAR Application
A low-profile wide-scanning conformal phased array (CPA), with cavity-backed stacked patch elements, is presented in this paper. To reduce the array profile, a partially dielectric-filled cavity is employed in each element, and to enhance its scanning performance, the cavity walls are deliberately modified. Finally, the designed element operates in a frequency band of 1.45∼1.75 GHz, with a profile of 0.086 ( is the free-space wavelength at 1.75 GHz), and achieves ±60° scanning in the E/H-planes, with the reflection coefficient below −7 dB. The proposed design method and all numerical results are experimentally verified by a 4 × 4 CPA prototype.
期刊介绍：
International Journal of Antennas and Propagation publishes papers on the design, analysis, and applications of antennas, along with theoretical and practical studies relating the propagation of electromagnetic waves at all relevant frequencies, through space, air, and other media.
As well as original research, the International Journal of Antennas and Propagation also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
