Abstract
A microwave antenna lead for feeding signals to high-voltage electrodes is described. The unit includes the receiving and transmitting microwave antennas, separated by a high-voltage insulator. The antennas are made as two symmetrical parts of a cut-across half-wavelength coaxial closely coupled resonator, and the insulator is made as a ceramic disk. The characteristics of the unit are presented. The high voltage is >60 kV, the microwave-signal transmission gain S 21 at the operating frequency is over 0.97, and the bandwidth at the level S 21 = −3 dB is more than 70%.
