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

Carrying structure of an active antenna in the aerospace industry uses basically fiber reinforced synthetic material in which heat conductive elements and/or elements conducting electromagnetic waves (electro, optic) are integrated into that support structure for the antenna.

Certain thermoplastics, notably high molecular weight, oriented amorphous or partially crystralline polyethylene are used as a cover for or directly as a window for IR equipment in aircraft, permitting direct exposure to the environment.
