This paper presents a genetically evolved antijamming beamforming array. The performance of a genetic algorithm (GA) is evaluated in situ as part of a hardware-in-the-loop optimization system. The GA was able to find reasonable beamformer settings to thwart a maximum of three stationary jammers while allowing reception of a signal of interest. Although the array operates in the 2.4 GHz 802.11g band,...
This paper presents the design of a wideband connected crossed-dipole array with dual-polarization for SATCOM. The element design is able to cover a bandwidth of approximately 2:1, with wider bandwidths possible depending mainly on array size and balun design. This design also allows wide scanning (up to +/- 60 degrees across the full bandwidth) because elements are compact. Because the crossed dipoles...
