摘要: 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.

摘要: A method of controlling an active antenna comprising a matrix of individual transmitting/receiving elements. Two optical frequencies are superposed to generate an optical beat signal in the microwave frequency range. After electrical/optical conversion the beat signal is fed with a defined phase and amplitude to the individual transmitting/receiving elements of the antenna.
