Abstract (en)
[origin: US4212014A] Bipolar switches in first conductive leads mounted in a dielectric panel are divided into successive groups of alternating polarity and additional pairs of leads are positioned in the panel adjacent each first lead to couple the groups of switches in each first lead in parallel. A reduced reversed biasing of the additional leads results in the first leads being selectively rendered discontinuous by the switches, changing the electrical characteristics of the panel to shift or focus a microwave beam passing through the panel. The additional pairs of conductive leads also operate as microwave elements to increase the bandwidth of the panel.
