Aslan, Y. (author), Roederer, A.G. (author), Fonseca, Nelson J.G. (author), Angeletti, Piero (author), Yarovoy, Alexander (author)An innovative reconfigurable beamforming network concept for multiple high-gain agile and mutually zero-forced beam generation is proposed. Four-port couplers and variable phase shifters are used to synthesize the network. A 2 beam by 7 element beam former is designed and fabricated as proof of concept. A static scenario with the two beams...conference paper 2024

Haider, S.N. (author), Yarovoy, Alexander (author), Roederer, A.G. (author)A frequency reconfigurable phased array element is presented. The operational band of the single port L/S-band antenna can be selected by modifying the element apertures with p-I-n diode switches. The antenna element satisfies strict requirements on its frequency band separation (2.2:1), size, feeding structure and control lines to be...journal article 2017
