POLYRHOMBIC ANTENNA (ALTERNATIVES)

FIELD: radio engineering; television, radio broadcasting and radio communication equipment operating in superhigh- and extremely-high frequency bands. ^ SUBSTANCE: proposed polyrhombic antenna has first and second rhombic antennas assembled of conductors disposed along rhomb sides and loaded into common active resistance equal to half the rhomb wave impedance, as well as first and second two-wire power lines. First rhombic antenna is connected to first power line and second one, to second power line. Connection points of power lines are disposed on same plane as active resistor and are equally spaced from bisectrix of mutual inclination angle of rhombic antennas. First and second two-wire power lines on side opposing angle vertex are integrated to form single two-wire line so as to ensure equal distances along first and second power lines between point of their integration and point of connection of first and second rhombic antennas. Pairs of rhombic antennas whose rhombs have their planes parallel to planes of first and second rhombic antennas can be connected along two-wire power lines so that active resistors were disposed on same straight line. As an alternative, pairs of rhombic antennas can be loaded into two-wire line matched to these pairs, with its leads connected to active resistances equal to its wave impedance. Linear dimensions of pairs of rhombic antennas may vary from pair to pair obeying geometric progression law. ^ EFFECT: enhanced gain and efficiency. ^ 5 cl, 14 dwg
