- Abstract
- A 5.3 GHz microstrip antenna for use in synthetic aperture radar (SAR) systems was developed with a composite sandwich construction, using composite laminates, Nomex honeycomb and aluminum alloy. This is the surface-antenna-structure (SAS) for application to load-bearing structural surfaces. The design concept originated from a composite sandwich structure and a multi-layer microstrip antenna. Design, fabrication and validation of structural/electrical performances were all demonstrated. To verify the structural rigidity, flexural behavior was observed under the three-point bending test and was compared with two kinds of composite sandwich beams consisting of CFRP-GFRP skins and Nomex honeycomb core. Electrical measurements of the fabricated antenna array were in good agreement with design requirements, and a comparative study found that SAS has good mechanical characteristics. The SAS concept can be extended to give a useful guide to manufacturers of structural body panels as well as antenna designers, promising innovative future communication technology.
