Antena de Microfita com Múltiplas Camadas para SAR Polarimétrico

Mateus Bonadiman, J. C. da S. Lacava, David Fernandes

Abstract


This paper presents a guideline to design dual-polarized stacked-coupled patch microstrip antennas for high-resolution SAR applications. In order to achieve concurrently high-isolation and good impedance matching for a required SAR frequency band, quarter-wave transformers are added at the antenna input ports. The design data are computed by using commercial CAD packages. To illustrate the proposal procedure, L-band (1.2 - 1.3 GHz) SAR antennas are analyzed. Two prototypes are synthesized and manufactured. The measured results are in good agreement with the CAD predictions.
