A microstrip antenna has an electrically conductive base plate carrying an electrically insulating substrate on top of which are a plurality of radiating patches, the improvement comprises establishing a relatively large spacing between the electrically insulating substrate and the base plate at lateral dimensions larger than lateral dimensions of the patches and in the vicinity of the patches and either through local elevations of the insulating substrate or by local indents in the base plate being vertically aligned with the patches.

Microstrip antenna

The present invention relates to a method for topographically mapping the surface of the Earth under utilization of measuring the altitude by means of radar, and under further utilization of a synthetic aperture for the radar, as well as an electronically controlled antenna lobe. In accordance with the preferred embodiment of the present invention, it is suggested to conically pivot the antenna lobe around a nadir, whereby pivoting of the center line follows a path such that the line constitutes the geneatrix of a cone.
