Plasma control of the directional pattern of a multislot waveguide antenna

Reflector plasma array antennas

“…A number of recent studies present results of inves tigations of plasma antennas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] including plasma array antennas [1-3, 7, 9, 11, 13, 14]. In [1-3, 7, 9, 11], a plasma array is employed as a reflector of ultrashort wave radiation.…”

“…A good agreement between the scattering radiation patterns of a plasma reflector and a metal reflector is reported. In [13,14], plasma is used for controlling the pattern of an array.…”

“…Plasma with the carrier concentration over the crit ical value (ω pe > ω) is used for creating dipole plasma antennas [4 6, 8, 10, 12, 15, 16], and plasma with the concentration below the critical value (ω pe < ω) is used for controlling the pattern of slotted waveguide plasma antennas [12][13][14]. LAYER OF A AN ANTENNA ARRAY A plasma antenna array was investigated with the use of an experimental test bench consisting of a her metic chamber, a model array antenna, a high voltage power source, a pulse generator, an energy storage, a roughing down pump, and a fiber recorder of optical radiation.…”
