On combine radiation properties of patch antenna cluster placed on small boxes

Technology of manufacturing thin antennas in a form of multilayer patches, combining their feed circuits, is becoming mature enough to be used in many new applications. Use of such antennas is particularly favourable, when the antennas are mounted directly on walls of objects on which antennas are supposed to be carried (mainly vehicles and spacecraft). Among most important shapes are boxes made of conductive walls. In our studies, we investigated different concepts of patch antenna placement on such boxes. Numerical analysis was run with full- wave methods and with the geometrical Ray-tracing method. Results of simulations were compared to experimental results.
